History of Estonia between 1800 BC - 501 BC
The beginning of the Bronze Age in Estonia is dated to approximately 1800 BC. The development of the borders between the Finnic peoples and the Balts was under way. The first fortified settlements, Asva and Ridala on the island of Saaremaa and Iru in the Northern Estonia began to be built. The development of shipbuilding facilitated the spread of bronze. Changes took place in burial customs, a new type of burial ground spread from Germanic to Estonian areas, stone cist graves and cremation burials became increasingly common aside a small number of boat-shaped stone graves.
About 7th century BC, a big meteorite hit Saaremaa island and created the Kaali craters. About 325 BC, the Greek explorer Pytheas possibly visited Estonia. The Thule island he described has been identified as Saaremaa by Lennart Meri, though this identification is not widely considered probable, as Saaremaa lies far south of the Arctic Circle.

Previous historical period: The Neolithic Period (-5000--1801) | Next historical period: The Iron Age (-500-1207)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.
