Hardeberga Church was built around the year 1200. It was enlarged and the vaulted tower and porch were added in the Middle Ages. The current tower dates mainly from the restoration made in 1909-1910.
The altarpiece dates from the early 17th century and the font from the Middle Ages. The decorated roof was painted by Godfrey Pettersson in 1909. In 2003 archaeologists found the previously unknown rune carving from the north wall.
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.
