According the legend the first church in Selaön island was built by St. Olaf (Olaf II of Norway) in early 1000s. The current Ytterselö Church dates however from the 1100s. In the late Middle Ages it was changed as a square form hall church with vaults. The funeral chapel of Soop på Mälsåker family was added in 1650. The new choir was completed in 1728.
The beautifully carved triptych dates from c. 1500 and is made in Antwerpen. The crucifix was also made around 1500 and the pulpit around 1600. There is also an unusual tomb in the churchyard; The grave of Hans Åkesson Soop has four pillars and there is stone relief of Soop and his wife.
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.
