Halk church is a whitewashed church with a lead covered roof, which consists of a Romanesque choir and nave. Later, an expansion towards the west was added, as well as a sacristy, weaponhouse, chapel and an east facing tower, which is rarely seen.
The alter tablet is a beautiful combination of parts from a late-gothic alter tablet, which has been inserted into a late-renaissance frame from around 1640.
The church has an unusually large amount of fixtures from the Middle Ages, including beautiful sitting Mary with child from ca. 1275. There is also a crucifix from the same era, with side figures, where Mary is original, while John is from the 1400s. A canopy tablet with the crowned and blessing Christ dates from ca. 1400. A processional crucifix is from the first quarter of the 1500s.
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.
