The Church of the Eremitani, or Church of the Hermits, is an Augustinian church of the 13th century. It was built in 1276 and dedicated to the saints Philip and James; it is however best known as degli Eremitani from the annexed old monastery, which now houses the municipal art gallery.
The chapel of SS. James and Christopher (Ovetari Chapel), formerly illustrated by Mantegna's frescoes, was largely destroyed by the Allies in World War II, because it was next to a German headquarters. There are more than 88000 fragments covering only 77 m2, while the original area covered several hundreds. Other artists whose frescoes are preserved in the church include Guariento and Ansuino da Forlì.
The church contains the tombs of Jacopo II da Carrara (d.1351) and Ubertino da Carrara (d.1345) da Carrara, lords of Padua, both by Andriolo de Santi (de Sanctis) and others. They were formerly in the church of Sant'Agostino, but were moved here after that church was razed in 1819.
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.
