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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
