The Influence of Arab architecture in Spain and Portugal
Arabic architecture in Spain and Portugal is one of the most important and richest in the world. Its influence is visible in the architecture of both countries, from the most iconic monuments to everyday buildings.
Introduction to Arabic Architecture in Spain and Portugal
Hispano-Muslim or Moorish architecture arrived in the Iberian Peninsula with the Islamic conquest in the 8th century. Muslims settled in the region for over 700 years, and during that period, their architecture had a great influence on the local culture.
The earliest influences of Arabic architecture can be seen in buildings constructed during the Umayyad Emirate and Caliphate period (711–1031). During this era, mosques, palaces, and fortresses were built that combined elements of Roman, Byzantine, and Arabic architecture.
Over time, Arabic architecture in the Iberian Peninsula evolved and acquired its own characteristics. Arabic architects used a variety of decorative elements and construction techniques to create buildings that were simultaneously beautiful and functional.
Unique Characteristics of Arabic Architecture
Arabic architecture in the Iberian Peninsula is characterized by a set of unique elements, the most important of which are the following:
Decorative Elements
The decorative elements of Arabic architecture are some of its most distinctive features. These elements are used to create intricate and harmonious patterns that fill buildings with life.
- Geometric motifs: These are the most common in Arabic architecture. They are used to create repetitive patterns that can be simple or complex. The most common geometric motifs are squares, rectangles, triangles, and circles.
- Floral motifs (ataurique): Another common decorative element. They are used to create lush patterns that evoke nature. The most common flowers in Arabic architecture are lotus flowers, orange blossoms, and hibiscus flowers.
- Calligraphic motifs (epigraphic): These are also an important decorative element. They are used to write verses from the Quran or religious phrases. Arabic calligraphy is a highly sophisticated art form and is used to create elaborate decorative patterns.
- Tiles and tilework (alicatados): Tiles are an essential component. They are used to create geometric, floral, or calligraphic patterns. The most common techniques in this architectural style are cuerda seca, cuenca o arista (molded tile), and zellige (mosaic tilework).
Other common decorative elements in Arabic architecture include plasterwork (yeserías), stucco, mosaics, and wood inlays (mocarabes and coffered ceilings).
Construction Techniques
Arabic architects used a variety of innovative construction techniques to create robust and elegant buildings:
- Archway system: A construction technique that uses a series of arches to support a roof or vault, creating spaces with a sense of spaciousness.
- Load-bearing walls: These are structural walls that support the weight of a building. They are used in Arabic architecture to provide great solidity to spaces.
- Horseshoe arch: A characteristic element of Andalusi architecture. It is characterized by its curved shape that closes below the radius point. It is used to create wide, bright spaces.
- Muqarnas vault: A vault formed by a series of prismatic decorative elements that hang like stalactites. It is used to create spaces of great ornamental richness.
- Half-orange dome: A dome shaped like a hemisphere. It is used to create spaces with a great sense of height.
Cultural Influences
Hispano-Muslim architecture in the Iberian Peninsula reflects the cultural influences of the various peoples who inhabited the region. Roman, Byzantine, and Christian elements can be seen in the buildings, creating a unique synthesis of styles.
- Roman elements are seen in Islamic architecture in the form of round arches, columns, and repurposed capitals.
- Byzantine elements are observed through domes and polychrome mosaics.
- Christian elements were later integrated in variants such as pointed horseshoe arches, bell towers, and shared decorative motifs.
Iconic Examples of Arabic Architecture
The Iberian Peninsula houses some of the most iconic examples of Islamic architecture. Among the most outstanding are:
