Poskær Stenhus is Denmark's largest round barrow, dating from the age of Funnelbeaker culture (around 3300 BC). The best view of this monument is from the north approach by the road through the hills of Mols Bjerge. The burial chamber has a diameter of more than 2 metres and a ceiling height of almost 1.8 metres. The chamber is surrounded by 23 kerb stones, some of which are more than 2.5 metres high. In 1859, the owner, Ole Hansen, started blasting the barrow stones to sell them as building material. He needed the money for his family and couldn't turn a proper living from the land where the barrow was. The barrow was rescued by local officials.
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.
