Olympia was site was a major Panhellenic religious sanctuary of ancient Greece, where the ancient Olympic Games were held every four years throughout Classical antiquity, from the 8th century BC to the 4th century AD. Today it is a UNESCO World Heritage Site and popular place to visit due large remains from Antiquity.
The site had been occupied since about 1500 BC, with a religious cult of Zeus developing around 1000 BC. The first Olympic festival was organized on the site by the authorities of Elis in the 8th century BC – with tradition dating the first games at 776 BC. Major changes were made to the site around 700 BC, including levelling land and digging new wells.
The earliest evidence of building activity on the site dates from around 600 BC. At this time the Skiloudians, allies of the Pisatans, built the Temple of Hera. The Treasuries and the Pelopion were built during the course of the 6th century BC. The secular structures and athletic arenas were also under construction during this period including the Bouleuterion. The first stadium was constructed around 560 BC and it consisted of just a simple track. The stadium was remodelled around 500 BC with sloping sides for spectators and shifted slightly eastward. Over the course of the 6th century BC a range of sports were added to the Olympic festival. In 580 BC, Elis, in alliance with Sparta, occupied Pisa and regained the control over the sanctuary.
The classical period, between the 5th and 4th centuries BC, was the golden age of the site at Olympia. A wide range of new religious and secular buildings as well as structures were made.
The Temple of Zeus was built mid 5th century BC. Its size, scale and ornaments were beyond anything previously constructed on the site. The Greek Baths and further sporting facilities, including the final iteration of the stadium, and the hippodrome (for chariot-racing) were constructed. The Prytaneion was built at the northwest side of the site in 470 BC.
In the late classical period, further structures were added to the site. The Metroon was constructed near the Treasuries around 400 BC. The erection of the Echo Stoa, around 350 BC, separated the sanctuary from the area of the games and stadium. The South Stoa was built at the southern edge of the sanctuary at approximately the same time.
The late 4th century BC saw the erection of the Philippeion. Around 300 BC the largest building on the site, the Leonidaion, was constructed to house important visitors. Due to the increasing significance of the games, further athletic buildings were constructed including the Palaestra (3rd century BC), Gymnasion (2nd century BC) and bath houses (c.300 BC). Finally, in 200 BC, a vaulted archway was erected linking the entrance of the stadium to the sanctuary.
During the Roman period, the games were opened up to all citizens of the Roman Empire. A programme of new buildings and extensive repairs, including to the Temple of Zeus, took place. In 150 AD, the Nympheum (or Exedra) was built. New baths replaced the older Greek examples in 100 AD and an aqueduct was constructed in 160 AD.
The 3rd century saw the site suffer heavy damage from a series of earthquakes. Invading tribes in 267 AD led to the centre of the site being fortified with material robbed from its monuments. Despite the destruction, the Olympic festival continued to be held at the site until the last Olympiad in 393 AD, after which the Christian emperor Theodosius I implemented a ban. The Temple of Zeus was apparently destroyed around 426 AD, during the persecution of pagans in the late Roman Empire, following an edict by Theodosius II enforcing the ban on pagan festivals. The workshop of Pheidias was turned into a Basilica and the site was inhabited by a Christian community. Archaeological evidence suggests that small scale Olympic events (perhaps in Christian guise) were still being held secretly until Justinian's plague and two earthquakes devastated the place mid 6th century. Repeated floods ensured that the settlement was finally abandoned altogether in the early 7th Century.

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.
