Located in the Kaylaka Park a few kilometers away from Pleven, Storgosia is ancient fortress dating back to the Roman era and containing the ruins of towers, gates, residential houses, a public storehouse and a large church believed to be constructed around the 4th century. Originally built as a road stop, it became a fortress to protect itself from raids and attacks.
The fortress existed until the end of the 6th century, when the settlement of the Slavs apparently led to its abandonment and during the rule of the Ottoman Empire the fortress was practically destroyed (probably in the 16th century), so that the stones could be used for the construction of a wall around the Turkish barracks in Pleven.
Archaeological excavations have been carried out on the site and a few basic structures of buildings can be seen.
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.
