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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
