St Francis church was originally part of a Franciscan monastery, and was alongside the Royal Palace. Today it can be found close to the Venetian Palace. It consists of a three-sided apse with a small chapel off the south side. Buttressing supported the external walls. It was built in the early years of the 14th century with funding supplied by Henry II, King of Cyprus who reigned from 1285 to 1324.
Henry's reign was far from peaceful. He saw the fall of Acre in 1291, his own imprisonment from 1306 to 1310, and the disbandment of the Knights Templars in 1313. In the latter years of his reign, however, not only did he fund the building of this church, but he saw the fortification of Famagusta, and the start of the rebuilding of St Nicholas Cathedral.
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.
