The structure of the St Peblig's Church has thirteenth century origins although much of the present fabric is of the fourteenth century. A tower and chapel were added in the sixteenth century, and there were further minor alterations in the eighteenth and ninteenth centuries before major restoration work was undertaken in 1894.
The church is constructed of coursed rubble walls with a slate roof and coped gables. It is notable for its imposing 3-storey western tower and has a high quality, late medieval arch-braced roof. There is a sixteenth century alabaster tomb in the north-eastern chapel, and some evidence of wall painting, including scrollwork in a tomb recess that is probably of medieval date.
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.
