When the capital of Spain was transferred from Toledo to Madrid in 1561, the seat of the Church in Spain remained in Toledo and the new capital had no cathedral. Plans to build a cathedral in Madrid dedicated to the Virgin of Almudena were discussed as early as the 16th century but even though Spain built more than 40 cities in the new world during that century and plenty of cathedrals, the cost of expanding and keeping the Empire came first and the construction of Madrid's cathedral was postponed. Making the cathedral the largest that the world had ever seen was then a priority, all other main Spanish cities had centuries old cathedrals, Madrid also has old churches but the construction of Almudena only began in 1879.
The cathedral seems to have been built on the site of a medieval mosque that was destroyed in 1083 when Alfonso VI reconquered Madrid.
Francisco de Cubas, the Marquis of Cubas, designed and directed the construction in a Gothic revival style. Construction ceased completely during the Spanish Civil War, and the project was abandoned until 1950, when Fernando Chueca Goitia adapted the plans of de Cubas to a baroque exterior to match the grey and white façade of the Palacio Real, which stands directly opposite. The cathedral was not completed until 1993, when it was consecrated by Pope John Paul II. On May 22, 2004, the marriage of King Felipe VI, then crown prince, to Letizia Ortiz Rocasolano took place at the cathedral.
The Neo-Gothic interior is uniquely modern, with chapels and statues of contemporary artists, in heretogeneous styles, from historical revivals to 'pop-art' decor. The Blessed Sacrament Chapel features mosaic from known artist Fr. Marko Ivan Rupnik.
The Neo-Romanesque crypt houses a 16th-century image of the Virgen de la Almudena. Nearby along the Calle Mayor excavations have unearthed remains of Moorish and medieval city walls.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
