San Giuseppe church was erected in 1756-1796 under the patronage of the Benedictine order. The church and an adjacent convent of nuns occupied a site where prior to the 1693 earthquake had been located the church of San Tommaso. The architect is unknown, but in the circle of Rosario Gagliardi. Like many local churches, the façade has three highly sculpted order, decorated with statues of Saints of the Benedictine orders, including Saints Benedict and Mauro above and St Gertrude and Scolastica below. Near the entrance are statues of St Gregory the Great and St Augustine by Giambattista Muccio in 1775. The entrance portals have iron grillwork screens (1774) by Filippo Scattarelli.
The interior has an oval layout, but kept a large choir and coretti situated over the entrance and flanking the nave, where the nuns could hear the mass while remaining cloistered. Over the vault is a fresco depicting the Glory of St Benedict with St Joseph (1793) by Sebastiano Monaco. The walls are elaborately stuccoed (1793) by Agrippino Maggiore and the Cultrera di Licodia Eubea. The altars (19th century) have elaborate scagliola, and have altarpieces by Tommaso Pollace and Giuseppe Crestadoro, depicting the Trinity, St Mauro, St Benedict, and Ste Gertrude. The pavement has white stone and maiolica tiles. The Vestibule has statues depicting St Benedict (17th century) and a silver-coated St Joseph (1785).
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.
