Himmelev Church dates probably from the late 1100s and it was built in Romanesque style. The tower and arches were added around 1300 as well as Gothic style windows. The tower was rebuilt of brick around 1550. The oldest item in church is a crucifix from the 1300s. The font dates from 1625 and pulpit from 1630. The altar was made by Anders Nielsen Hatts workshop in Roskilde in the early 1600s.
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.
