St Peter's Church stands at the heart of the upper town, which had fortifications in the Middle Ages. Its entrance portal looks out onto a square on which stand a mission cross and the portal of the clergy house, both classified monuments historiques as well.
St Peter's Church is a former collegiate church with a Romanesque tower and a modern belltower. Its 12th-century nave and side aisles have capitals. The transept also dates back to the 12th century; yet its chevet was modified in the 18th and 19th centuries.
The church houses the tombstone of Saint Euchaire, a 16th-century Renaissance gisant in a funeral niche. The interior is also decorated with 18th-century paintings and old mural paintings.
The western portal was modified but a part of the old sculpture is still visible today.
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.
