Spain’s Architecture Guide: 15 Architectural Landmarks to Visit in Spain

The history of architecture in Spain is rich and diverse, reflecting the various influences that shaped the country’s culture and identity. Spanish architecture demonstrates its builders’ and designers’ creativity and skill from ancient Roman monuments to modern masterpieces. The most distinctive feature of Spanish architecture is the blending of different styles and elements from different periods and regions. The Mudéjar style, which emerged in the 12th century, combined Romanesque, Gothic, and Renaissance features with Islamic motifs and techniques. The other example is the Modernisme style, which flourished in the late 19th and early 20th centuries and incorporated elements of Art Nouveau, Gothic, and Catalan traditions. Some of the most famous and influential Spanish architects include Antoni Gaudí, who created unique and organic structures such as the Sagrada Família in Barcelona; Santiago Calatrava, who designed innovative and elegant bridges, buildings, and sculptures around the world; and Rafael Moneo, who won the Pritzker Prize in 1996 for his contribution to contemporary architecture. Spanish architecture continues to evolve and inspire as new generations of architects explore new forms and materials.

01. Alhambra

The Alhambra is an ancient palace and fortress complex in Granada, Spain. It is one of the most famous monuments of Islamic architecture and one of the best-preserved palaces of the historic Islamic world. It also contains notable examples of Spanish Renaissance architecture. The complex was begun in 1238 by Muhammad I Ibn al-Ahmar, the first Nasrid emir and founder of the Emirate of Granada, the last Muslim state of Al-Andalus. It was built on the Sabika hill, an outcrop of the Sierra Nevada, which had been the site of earlier fortresses and the 11th-century palace of Samuel ibn Naghrillah. The Alhambra covers an area of 9 hectares (22.2 acres), with more than 1.6 kilometers (1 mile) of walls, 30 towers, and numerous smaller structures. It is surrounded by defensive walls and has three main sections: The Alcazaba, a military base that housed guards and their families; the palatial zone, which contained several palaces for the sultan and his kin; and the Medina, a quarter where court officials lived and worked. The Nasrid palaces were divided into three independent areas: the Mexuar, a semi-public part of the palace for justice administration and state affairs; the Comares Palace, the official residence of the sultan that was comprised of several rooms that surrounded the Court of the Myrtles, an outdoor area containing a large central pond lined with myrtle bushes; and the Palace of the Lions, a private area of the palace for the king and his family and mistresses.

The Alhambra is known for its elaborate decoration, which features geometric patterns, arabesques, calligraphy, and colorful tiles. The architecture reflects the influence of various cultures and styles, such as Roman, Visigothic, Byzantine, and Persian. The most distinctive feature of the Alhambra is the use of the muqarnas, a type of vaulting that creates a honeycomb-like effect on the ceilings and arches. The muqarnas were used to create intricate and varied forms, such as stalactites, domes, and stars. The Alhambra also contains examples of Spanish Renaissance architecture, such as the Palace of Charles V, a 16th-century building that contrasts with the Nasrid palaces in its classical style and symmetrical layout. The palace was commissioned by Charles V, the Holy Roman Emperor and King of Spain, who wanted to establish his residence in the Alhambra. The palace was left uncompleted in the early 17th century and was never used by the king. The palace contains a circular courtyard and a museum of fine arts. The other important structure in the Alhambra is the Patio of the Lions, or Courtyard of the Lions, a courtyard that was part of the Palace of the Lions. The courtyard is named for the central fountain, surrounded by twelve lions that spewed water jets. The fountain is supported by a large marble basin that rests on the backs of the lions. The fountain symbolizes the Nasrid dynasty and represents the Garden of Eden. The courtyard is also decorated with columns, arches, and carved plasterwork.

02. Sagrada Familia

The Sagrada Familia is a church under construction in Barcelona, Catalonia, Spain. It is the largest unfinished Catholic church in the world and a UNESCO World Heritage Site. The construction of the Sagrada Familia began in 1882 under the architect Francisco de Paula del Villar. In 1883, Antoni Gaudí became the chief architect and transformed the project with his unique style. Gaudí devoted the rest of his life to the church and died in 1926, leaving less than a quarter of the project completed.

The Sagrada Familia has three grand façades: the Nativity, the Passion, and the Glory. Each one represents an aspect of the life of Jesus Christ. The Nativity façade was the first to be built and the only one that Gaudí saw finished. It depicts scenes from the birth and childhood of Jesus, with a rich ornamentation of natural and religious symbols. The Passion façade was built later, following the designs of Gaudí. It portrays the suffering and death of Jesus with a stark and angular style that contrasts with the Nativity façade. The Glory façade is still under construction and will be the largest and most elaborate of the three. It will illustrate the glory and judgment of Jesus, as well as the ascension of the faithful to heaven. The Sagrada Familia has 18 towers, of which 13 have been built. The towers represent the 12 apostles, the four evangelists, the Virgin Mary, and Jesus Christ. The tower of Jesus will be the tallest, reaching 170 meters (558 feet) in height, making it the highest point in Barcelona. The towers are decorated with ceramic tiles and sculptures of saints, angels, and biblical figures. They also have bells that ring at different times of the day and night.

The interior of the Sagrada Familia is inspired by nature and geometry. The main nave has a vaulted ceiling that resembles a forest canopy, supported by columns that branch out like trees. The windows are filled with stained glass, which creates a colorful and luminous atmosphere. The altar is in the center of the cross-shaped floor plan, surrounded by a baldachin and a crucifix. The crypt, where Gaudí is buried, is located under the altar and contains a museum displaying models, drawings, and church photographs. The Sagrada Familia is a masterpiece of Gothic Revival and Art Nouveau architecture and a personal expression of Gaudí’s faith and vision. The church combines various historical and cultural elements, such as Catalan, Byzantine, Romanesque, and Renaissance styles. The church also incorporates innovative techniques and materials like iron, concrete, and ceramics. 

03. Park Güell

Park Güell is a large park in Barcelona, Spain, that features gardens and architectural elements designed by the famous Catalan architect Antoni Gaudí. The park covers an area of 15 hectares (37.1 acres) and is located on Carmel Hill, near the Collserola mountain range. Park Güell is one of the most popular attractions in Barcelona and has been a UNESCO World Heritage Site since 1984. Park Güell was commissioned by Eusebi Güell, a wealthy entrepreneur and fan of Gaudí, who wanted to create a residential estate with artistic and naturalistic features. The project started in 1900 and lasted until 1914, but only two houses were built, and the estate was never completed. In 1926, the park was opened to the public as a municipal garden.

Park Güell showcases Gaudí’s artistic and architectural style, inspired by organic shapes and natural elements. He used a technique called trencadís to create mosaic patterns with broken ceramic tiles. He also experimented with new structural solutions based on geometry and the analysis of forms. He applied his creative and innovative ideas to various park elements, such as the entrance, the main terrace, the viaducts, the colonnaded hall, and the Gaudí House Museum. The entrance of Park Güell is marked by two whimsical buildings that resemble gingerbread houses. They were originally intended to be the porter’s lodge and the administration office. Between them, there is a monumental staircase that leads to the main terrace. On the staircase, there is a colorful mosaic sculpture of a salamander, symbolizing the park and Gaudí’s work.

The main terrace of Park Güell is a large esplanade surrounded by a wavy bench covered with trencadís. The bench offers a panoramic view of the city and the sea. The terrace is supported by a series of columns that form a colonnaded hall underneath. The hall was designed to be a market for the estate’s residents, but is now used as a venue for cultural events. The hall’s ceiling is decorated with circular medallions that represent the four seasons and the moon’s phases. Park Güell also contains several viaducts that cross the hill and connect different parts of the estate. The viaducts are made of stone and brick and have organic shapes that blend with the natural environment. They are supported by inclined columns that resemble tree trunks. Some of the viaducts have openings that allow the passage of light and air. The viaducts are examples of Gaudí’s skill in creating harmonious and functional structures.

04. Casa Batlló

Casa Batlló is a building in the center of Barcelona, Spain. It was designed by Antoni Gaudí and is considered one of his masterpieces.

Casa Batlló is made of stone, metal, wood, ceramic, and glass. It has a colorful mosaic made of broken ceramic tiles (trencadís) on its façade, which gives it a distinctive appearance. The façade also has irregular oval windows, flowing sculpted stonework, and balconies that resemble skulls and bones. Casa Batlló is an example of the Modernisme or Catalan Modernism style, influenced by the European Art Nouveau movement. Gaudí was one of the leading architects of this style, which aimed to create organic and natural forms inspired by nature and Catalan culture.

Casa Batlló also reflects Gaudí’s vision and symbolism. He incorporated elements of Catalan nationalism, such as the four bars of the Catalan flag on the façade and the cross of Saint George (the patron saint of Catalonia) on the roof. In interior decorations, he also used religious motifs, such as the Holy Family and the Eucharist. He also created fantastic and mythical images, such as the dragon-like roof, representing the legend of Saint George slaying the dragon. Casa Batlló has been a UNESCO World Heritage Site since 2005, along with other works of Gaudí in Barcelona. It is also a cultural and tourist attraction visited by people worldwide. It offers visitors various exhibitions, events, and activities, such as a virtual reality tour, a light show, and an outdoor escape game.

La Pedrera has a unique and innovative structure that consists of two blocks of apartments connected by two large courtyards. The façade is not a load-bearing wall but a curtain wall made of stone blocks attached to the structure by metal components. The façade has a wavy shape that creates a dynamic and organic impression.

La Pedrera also features twisted wrought iron balconies that complement the stone façade. The ironwork was made from scrap metal and has a complex and expressive design. Some balconies resemble plants and animals, while others are abstract and geometric. The ironwork is considered a precursor of the abstract sculpture of the 20th century. La Pedrera has a free-plan floor that allows for flexible and functional spaces. The apartments have different shapes and sizes, depending on the position and orientation of the building. The apartments have large windows that provide natural light and ventilation. The windows can be opened and closed by counterweights and pulleys.

La Pedrera has an underground garage that was one of the first in the city. The garage has ramps that connect to the courtyards and allow the vehicles to enter and exit. The garage also has a ventilation system that prevents the accumulation of gas and smoke. The garage was a novelty and a convenience for the residents of the building. La Pedrera has a spectacular terrace on the roof, offering a panoramic view of the city. The terrace has several chimneys, ventilation towers, and staircases with sculptural and artistic value. The chimneys have different shapes and decorations, some inspired by medieval helmets and warriors. The ventilation towers have ceramic tiles reflecting sunlight and creating colorful effects.

The Royal Palace of Madrid is the official residence of the Spanish royal family in the city of Madrid. The royal family does not live there and only uses it for state ceremonies. The palace is the largest in Western Europe and one of the largest in the world. It has a floor area of 135,000 square meters (1,453,140 square feet) and 3,418 rooms. The Royal Palace of Madrid stands on the site of a former Muslim fortress built by Emir Muhammad I of Córdoba in the 9th century. The fortress was later used by the kings of Castile and became the Royal Alcázar of Madrid. The Alcázar burned down in 1734, and King Philip V ordered a new palace to be built in the same location.

The construction of the Royal Palace of Madrid began in 1738 and lasted until 1755. The design was influenced by the Italian architect Filippo Juvarra, who proposed a grandiose project with a Baroque style. Juvarra died before the work started, and his assistant, Giovanni Battista Sacchetti, took over the project. Sacchetti simplified Juvarra’s plan and gave the palace a more classical appearance. The Royal Palace of Madrid was completed by other architects, such as Ventura Rodríguez, Francesco Sabatini, and Martín Sarmiento, who added or modified some parts of the building. The palace has a rectangular shape with four facades and four courtyards. The main facade faces the Plaza de Oriente and has a large balcony where the royal family appears on special occasions. The palace is surrounded by gardens, such as the Campo del Moro and the Sabatini Gardens.

The interior of the Royal Palace of Madrid is richly decorated with paintings, sculptures, frescoes, tapestries, and furniture.

The Mosque-Cathedral of Córdoba is a unique architectural monument in Córdoba, Spain. It reflects Andalusia’s religious and cultural diversity, as it was built and modified by different civilizations over the centuries. It is one of the world’s largest and most impressive examples of Islamic art and architecture. The Mosque-Cathedral of Córdoba was originally a Visigothic church built in the sixth century. In 784, the Umayyad ruler Abd al-Rahman I bought the church and transformed it into a mosque. He used local materials, such as stone, brick, wood, and marble, to create a spacious and elegant prayer hall. Its successors expanded the mosque in the ninth and tenth centuries, adding more naves, arches, columns, and mosaics.

The most distinctive feature of the Mosque-Cathedral of Córdoba is the hypostyle hall, which has 850 columns supporting double-tiered horseshoe arches. The arches contrast red and white colors, symbolizing the harmony of Islamic and Christian cultures. The columns are made of different materials, such as jasper, porphyry, and granite, and some of them were reused from Roman and Visigothic buildings. The rectangular hall is 180 meters (591 feet) by 130 meters (427 feet). The Mosque-Cathedral of Córdoba also has a mihrab, or prayer niche, which faces south instead of the usual direction of Mecca. The mihrab is a small octagonal chamber decorated with exquisite Byzantine-style mosaics and gold. It has a dome carved from a single block of white marble shaped like a shell. The mihrab is considered one of the masterpieces of Islamic art.

In 1236, after the Christian reconquest of Córdoba, the Mosque-Cathedral of Córdoba was converted into a cathedral. The Christians added a Gothic nave, a Renaissance choir, a Baroque chapel, and a bell tower, among other elements. The cathedral occupies about one-third of the original mosque area and contrasts with the Islamic style of the rest of the building. The cathedral is dedicated to the Assumption of the Virgin Mary and houses several tombs of Spanish kings and nobles. The Mosque-Cathedral of Córdoba is a remarkable example of Spain’s coexistence and interaction of different cultures and religions.

It was first documented in the 12th century as a wooden fortress of the Almoravids. It became a royal residence of the Castilian kings in the 13th century and was expanded and renovated over the centuries. It witnessed important events, such as the coronation of Isabel the Catholic in 1474, the signing of the Concord of Segovia in 1475, and the wedding of Philip II and Anna of Austria in 1570.

The Alcazar of Segovia also served as a state prison, a Royal Artillery College, and a military academy. It suffered a fire in 1862, destroying most roofs and ceilings.

12. El Escorial

El Escorial is a historical residence of the King of Spain located in San Lorenzo de El Escorial, 45 kilometers (28 miles) northwest of Madrid. It was built between 1563 and 1584 by order of King Philip II, who wanted a building to serve as a burial place for his father, Charles V, a monastery, and a palace. El Escorial is the largest Renaissance building in the world and a UNESCO World Heritage Site. The main architect of El Escorial was Juan Bautista de Toledo, who designed the ground plan on a gridiron scheme, recalling the grill on which Saint Lawrence, the patron of the building, was martyred. After his death, Juan de Herrera took over the project and completed it in 1584. The style of El Escorial is known as Herrerian, characterized by its simplicity, symmetry, and geometric rigor. The building is made of granite and slate and has four principal stories with large towers at each corner.

El Escorial consists of two architectural complexes: the royal monastery and La Granjilla de La Fresneda, a royal hunting lodge and monastic retreat about five kilometers away. The royal monastery has several functions: a basilica, a royal palace, a pantheon, a library, a museum, a university, a school, and a hospital. The basilica is the complex’s centerpiece, with a dome that rises 92 meters (302 feet) above the ground. The royal palace occupies the northeastern part of the building and includes the apartments of the king and the queen, the hall of battles, and the hall of mirrors. The Pantheon is a circular crypt where the remains of most of the Spanish kings and queens are buried. The library is one of the most important in Europe, with more than 40,000 books and manuscripts. The museum displays paintings, sculptures, tapestries, and other artworks donated by the crown. The university and the school were founded by Philip II to educate the monks and the nobles. The hospital was intended to care for the sick and the poor. 

El Escorial was decorated by many notable Spanish and Italian artists of the 16th and 17th centuries, such as El Greco, Luca Giordano, and Claudio Coello. The interior of the building reflects the religious and political ideals of Philip II, who wanted to create a monument to Spain’s role as a center of the Christian world. The decoration was carefully coordinated with the architecture and the sculpture to create a unified artistic effect. The sober statue of Saint Lawrence on the main façade and the six statues of Old Testament kings on the façade of the basilica prepare the way for a splendid display of saints and kings inside the basilica. The frescoes, paintings, and altarpieces depict scenes from the Bible, Spain’s history, and the saints’ lives. The most famous artwork in El Escorial is The Martyrdom of Saint Maurice and the Theban Legion, painted by El Greco for the chapter house. El Escorial also has extensive gardens and courtyards, such as the Garden of the Friars, the Garden of the Kings, and the Courtyard of the Evangelists. The gardens are designed in the Italian and French styles, with fountains, statues, hedges, and geometric patterns. The courtyards are surrounded by arcades and columns and provide natural light and ventilation to the interior rooms. The gardens and courtyards also serve as places for recreation, meditation, and ceremonies.

15. Royal Alcazar of Seville

The Royal Alcazar of Seville is a historic royal palace in Seville, Spain. It is the oldest palace in the world that is still in use by the royal family. It covers an area of 7 hectares (17.3 acres) and consists of several buildings and gardens. The palace reflects the diverse cultural influences that shaped its history, from the Islamic era to the Christian reconquest and the Renaissance period. The Royal Alcazar of Seville was originally a fortified complex built by the Umayyad Caliphate in the 10th century on the site of a Visigothic basilica. It was expanded and renovated by the Abbadid and Almohad dynasties in the 11th and 12th centuries, respectively. The palace became a symbol of the power and wealth of the Muslim rulers of Al-Andalus, who decorated it with elaborate geometric patterns, arabesques, calligraphy, and tiles.

In 1248, Seville was conquered by the Castilian king Ferdinand III, who converted the Royal Alcazar of Seville into his residence. He preserved some of the Islamic features but added new Gothic and Romanesque elements. His son, Alfonso X, continued the modifications and built the Gothic Palace, which housed the royal treasury and archives. The palace also hosted important events, such as the wedding of Ferdinand IV and Constance of Portugal in 1302. The most significant transformation of the Royal Alcazar of Seville occurred in the 14th century, under the reign of Pedro I. He commissioned the construction of a new palace within the old complex known as the Mudejar Palace. This palace is considered the masterpiece of the Mudejar style, which combines Islamic and Christian elements. The palace features a stunning façade, a magnificent courtyard, and richly decorated halls and chambers. Pedro I also built the Baths of Lady Maria de Padilla, a series of underground cisterns that collect rainwater.

The Royal Alcazar of Seville continued to evolve in the following centuries as different monarchs added or altered parts according to their tastes and needs. The Catholic Monarchs, Isabella I and Ferdinand II built the Hall of Justice and the Hall of the Catholic Kings, where they received Christopher Columbus after his first voyage. Charles V, the Holy Roman Emperor, ordered the construction of a Renaissance-style palace, which contrasts with the Mudejar Palace. He also enlarged the gardens and introduced exotic plants and animals. The Royal Alcazar of Seville is a UNESCO World Heritage Site and a major tourist attraction. It offers visitors a glimpse into Spain’s rich and diverse history and a splendid display of art and architecture. The palace also serves as a venue for cultural events, such as concerts and exhibitions. The palace has also been used as a filming location for movies and TV shows, such as Lawrence of Arabia and Game of Thrones.
