Almudena Cathedral Crypt

The Cathedral of the Almudena (Santa María la Real de La Almudena) is Madrid's main Roman Catholic cathedral, built on Calle de Bailén directly adjacent to the Royal Palace on the city's western escarpment. Construction began in 1883 following a design by the Marquis of Cubas in Neo-Gothic style, but proceeded slowly through political instability, the Spanish Civil War, and repeated changes of architect and stylistic direction. The cathedral was finally consecrated by Pope John Paul II in June 1993 — 110 years after work began — making it one of the longest cathedral construction projects in modern European history. The dedication to the Almudena derives from the medieval legend of the Virgen de la Almudena, whose image was allegedly concealed within the city walls during the Moorish occupation and rediscovered when Alfonso VI reconquered Madrid in 1083. The crypt beneath the main cathedral is the oldest part of the complex, retaining a Romanesque-Byzantine character entirely distinct from the Neo-Gothic nave above. Built between 1884 and 1911 to designs by the Marquis of Cubas, it features low semicircular arches, columns with carved capitals, and vivid polychrome decoration restored in the 20th century. The Crypt Museum, accessible from a separate entrance on the south side of the building, houses medieval religious art including carved capitals, sculptures, and liturgical objects from earlier ecclesiastical buildings on this site. The main cathedral interior is notable for its unusual colour scheme — pale Neo-Gothic stonework combined with a colourful ceiling installed in 2001 — and for royal connections including the 2004 wedding of King Felipe VI and Queen Letizia. The adjacent Royal Palace and the sweeping Plaza de la Armería between them form one of Madrid's most powerful monumental ensembles.
