Päijälä hill fort is an Iron Age hill fort by the Lake Saaresjärvi in Kuhmoinen. The abundance of artefacts found at the Päijälä hill fort makes it nationally significant. The fort is thought to have been used since at least the 12th century. Kuhmoinen was then a borderland between Häme and Carelian tribes who fought over the ownership of wilderness areas.
The fort hill rises 25 metres above the surrounding terrain, and looking from above you can see the fort is built in a roughly circular form. The slopes of the hill are extremely steep from three sides.
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.
