The Saint Sebastian Church is a 16th-century church in central Madrid. The name arises from a devotional chapel which was found along the route to the Basilica of Nuestra Señora de Atocha, founded in 1541. The first architect around 1550 was Antonio Sillero, who also finished the Chapel of the Sagrado Corazón. This church like that of San Luis conserved for years the rights of asylum for those escaping official persecution. More chapels and enlargements were added by Antonio de la Tijera, Juan de Bulga Valdelastras, and Juan de Obregón between 1595 and 1598. The tower was built in 1612 by Lucas Hernández.
During the Spanish Civil War, the church was sacked by Republican forces, before it ended up being almost destroyed during a bombing raid by the Nationalists around November 20, 1936. This caused many of the works to be transferred to other sites. The church was rebuilt in a different orientation by Francisco Íñiguez Almech between 1943 and 1959.
The Chapel of Our Lady of Bethlehem, known as the 'chapel of the architects', was built in 1693 with Francisco Moreno as director of the works, and remodeled by Ventura Rodríguez in 1766-1768. Both Ventura Rodríguez and Juan de Villanueva are buried here. The chapel is to the right of the entrance, protected by a crystal gate.
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.
