The Ancient Agora of Classical Athens is the best-known example of an ancient Greek agora (central public space in ancient Greek city-states), located to the northwest of the Acropolis and bounded on the south by the hill of the Areopagus and on the west by the hill known as the Agoraios Kolonos, also called Market Hill. The Agora's initial use was for a commercial, assembly, or residential gathering place.
Agora contains several remains of ancient temples and buildings. Temple of Hephaestus is one of the best-preserved Greek temples, built around 450 BCE. The excavations has uncovered most of the over 30 known major buildings from the Agora, along with thousands of artifacts. Conservation efforts have restored thousands of pieces of pottery and amphora (the standard storage vessel of the ancient world), studied thousands of marble statues and reliefs, and analyzed the remains of human and animal bones to give us a better understanding of what life was like in the ancient Athenian world.
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.
