St. Olav's Church stone church was built before 1150 and probably Telemark's largest stone church in former times. It had a number of unusual building features, including lektorium and a separate room for earthly values, which today is called 'Mary's Chapel'. Probably the church was the main church in Grenland, a kind of 'county church' and therefore had the highest status of all churches in the area. Today the church ruins are located next to the newer Bamble Church.
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.
