The Royal Basilica of Our Lady of Atocha is one of the six basilica churches in Madrid. The buildings on the site have a long history. The original name refers to a lost icon from a chapel which was found during the time of the Reconquista. The old church was in disrepair and rebuilt in the 1890s in a Neo-Byzantine style designed by Fernando Arbós y Tremanti.
The church was destroyed during the Spanish Civil War and reconstruction completed in 1951.
Adjacent to the church is the Pantheon of Illustrious Men or Panteón de Hombres Ilustres of Madrid. It holds the remains of only a former president of the council of ministers, José Canalejas, however it also contains a number of interesting monuments from and just after the turn of the 19th century.
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.
