Madrid's architectural landscape is a fascinating journey through centuries, reflecting its transformation from a modest fortress into a majestic European capital. Each historical period has left its unique mark on the city's streets and squares, creating a multi-layered and eclectic urban scenery.
The Middle Ages and Mudejar Heritage
Before Madrid became the capital, its architecture was similar to other Castilian towns. Only fragments of the defensive wall remain from the earliest Arab period. However, a significant legacy of that era was the Mudejar style—a unique phenomenon in which Christian architectural forms were combined with Moorish decorative techniques. Striking examples of this style are the brick bell towers of the churches of San Nicolás de los Servitas and San Pedro el Viejo, which remain some of the oldest structures in the city.
Habsburg Madrid: Austerity and Grandeur (16th–17th Centuries)
With the transfer of the capital in 1561 by King Philip II, Madrid's "Golden Age" began. The architecture of this period, known as the Austrian Habsburg style or Herreriano (named after architect Juan de Herrera), is characterised by austerity, monumentality, and minimal decoration. Characteristic features include red brick, granite, and dark slate roofs. The main symbol of the era is Plaza Mayor—a rectangular square surrounded by buildings in a unified style, which became the centre of public life. Other iconic buildings of that time include the Palace of Santa Cruz and the Casa de la Villa in Plaza de la Villa.
The Bourbon Era: Baroque and Neoclassicism (18th Century)
With the arrival of the Bourbon dynasty, Madrid's architecture experienced strong French and Italian influence. Lavish and dynamic Baroque can be seen in the design of the Toledo Bridge (Puente de Toledo) and the façade of the Municipal Museum. However, the true transformation of the city is linked to the reign of Charles III, the "King-Mayor". He sought to turn Madrid into one of the great capitals of Europe by initiating the construction of many buildings in the Neoclassical style. During this period, masterpieces such as the Prado Museum building (architect Juan de Villanueva), the monumental Puerta de Alcalá gate, and the famous Cibeles and Neptune fountains were created, shaping the appearance of the Paseo del Prado.
19th and Early 20th Century: Eclecticism and Modernism
In the 19th century, the demolition of old city walls and the implementation of "Plan Castro" led to the city's expansion and the emergence of new districts with a rectangular street grid, such as the prestigious Salamanca district. Eclecticism, mixing elements of different styles, dominated architecture. In the early 20th century, the city's main construction project became the laying of Gran Vía, which turned into a true exhibition of architectural achievements of its era. Here one can find French style (the Metropolis building), Art Deco (the Telefónica building), and elements of Expressionism. Although Madrid Modernism (Art Nouveau) is not as famous as Catalan Modernism, it gifted the city such gems as the Longoria Palace (now the SGAE headquarters).
Contemporary Architecture (Late 20th – 21st Centuries)
After the period of dictatorship, Madrid's architecture received a new impulse for development. The urban landscape was supplemented with bold contemporary projects. The symbol of the new business Madrid became the skyscraper complex "Four Towers" (Cuatro Torres Business Area) in the north of Paseo de la Castellana. Renovation projects breathed new life into historical buildings: a former power station became the CaixaForum cultural centre with a unique vertical garden, while the expansion of the Reina Sofía Museum designed by Jean Nouvel and the new terminal of Barajas Airport became examples of an innovative approach to architecture. These projects demonstrate how Madrid continues to develop, harmoniously combining rich historical heritage with avant-garde solutions.
