The famous Kvitsøy Stone Cross was erected between 800–1050 AD. Some say it was put there by English missionaries in the 900s while others claim it was raised by Erling Skjalgsson and Olav Haraldsson, Viking chiefs, in 1016. There are a number of large stone crosses along the west coast of the Norway. Kvitsøy is first mentioned in the Snorre Saga, where Snorre records a truce being made between King Olaf II of Norway later to be known as St. Olav (Hellige Olav) and Erling Sjalgsson, under the stone cross.
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.
