Bollnäs church was originally built in the 14th and 15th centuries. One opening is known to have taken place November 3, 1468, probably concerning the church tower. Later alterations include the addition of the north and south transepts, built in 1753-1755.
The church holds a larger collection of wooden medieval sculptures than any other parish church in the Nordic countries. Three of the altarpieces are major works of art from the late 15th century or early 16th century, including an altarpiece dedicated to Virgin Mary, made byHaaken Gulleson c. 1520. Also dating from late 15th century or early 16th century is the most valuable eucharistic chalice, with its paten (a small plate).
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.
