Samuel's Fortress in the old town of Ohrid was built during the rule of Tsar at the turn of the 11th century. Today, 18 towers and four gates still remain from the original structure. With its strategic location overlooking the town and the lake, it provides an ideal place for taking in the whole panorama of Ohrid and its surroundings. It was heavily restored in 2003 with the addition of entirely new battlements where none had survived.
According to recent excavations by Macedonian archaeologists, it was contended that this fortress was built on the place of an earlier fortification, dated to the 4th century BC, which was probably built by King Philip II of Macedon.
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.
