Kläckeberga Church was built in the early 13th century, but was subsequently burned by the Danes in 1611. Today, the interior of the church consists mostly of furnishings and objects from the 18th century and later.
The church originally had three floors: a cellar, main floor (the present church hall) and a larger hall above that. In addition, there was once a shooting attic above that hall. So Kläckeberga Church was also once a fortified church, surrounded by several earthwork walls and moats. Historical notes from the 15th century also indicate that various garrisons were stationed in this church during the many battles for Kalmar and Kalmar Castle.
Today the most significant artefact in the church is a altarpiece painted by Herman Han in 1616. It was transferred to Sweden as a loot from Poland during the Thirty Years War.
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.
