Mycenae is an archaeological site near Mykines in Argolis, north-eastern Peloponnese, Greece. In the second millennium BC, Mycenae was one of the major centres of Greek civilization, a military stronghold which dominated much of southern Greece, Crete, the Cyclades and parts of southwest Anatolia. The period of Greek history from about 1600 BC to about 1100 BC is called Mycenaean in reference to Mycenae. At its peak in 1350 BC, the citadel and lower town had a population of 30,000 and an area of 32 hectares.
In 1999, the archeological site of Mycenae was added to the UNESCO World Heritage List, along with the nearby site of Tiryns, because of its historical importance as the center of the Mycenaean civilization, its outstanding architecture, and its testimony to the development of Ancient Greek civilization.
The stone architecture of Mycenae is unique in its kind, influenced by many civilizations like the Minoans in Crete. The archaeological excavations which began during the second half of the 19th century brought to light important architectural remains from the Mycenaean civilization including palaces, fortresses, settlements and burial monuments. The Mycenaean fortresses that lie on top of the rocks dominate the surrounding area, encircled by the strong walls. Of high interest are the palaces which are built in prominent locations and constitute building complexes and cobbled yards.
The characteristic Mycenaean tombs are also an important part of its architecture, the most famous being the tomb of Agamemnon (the Treasury of Atreus) which is in the form of a tholos. Nearby are other tombs, possibly Agamemnon ancestors. One of the distinctive features of the Mycenaean architecture is the very large stone blocks which characterize the brilliant fortification structures like the fortifying walls of the Acropolis, the Lion Gate and the Cyclopean walls (the myth says that they were constructed by the Cyclops).
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.
