San Pedro church is believed to be located over a previous edifice housing the remains of the Córdoban martyrs Januarius, Martial and Faustus, dating to the 4th century AD. After the conquest of the city by king Ferdinand III of Castile (1236), a church dedicated to St. Paul was built here in his program of construction to give a Christian appeal to the previously Muslim city. Construction began in the late 13th century and was completed in the early 14th century.
The edifice's current appearance date mostly to later restorations. Part of the bell tower and two of the medieval gates have survived, a new one having been added by architect Hernán Ruiz II in 1542. In 2006, the church was elevated to the status of minor basilica by Pope Benedict XVI.
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.
