The original Vallentuna church was built around 1190. The granite church consisted of a nave, choir and tower. The sacristy was added in the 13th century. The church was enlarged in the 15th century and brick vaults were constructed in 1763. The chapel of Klingspor family was built in the 17th century. Vallentuna church was badly damaged by fire in 1856. The church was restored and the exterior was strongly reshaped.
There are several examples of rune carvings in Vallentuna church: stone-cutters who carved their names in runes when the church was being built in the late 12th century, a rune stone telling of a shipwreck mortared into the wall, and one of Jarlabanke’s own rune stones. This last stone must have cracked at some point and new carving was made on the back. On the stone, Jarlabanke tells us that he built an assize place and that he alone made all the decisions in the region. Half of a rune stone stands by the eastern wall of the cemetery.
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.
