Acrocorinth is a monolithic rock overlooking the ancient city of Corinth, Greece. It is one of the most impressive acropolis of mainland Greece.
The Acrocorinth was continuously occupied from archaic times to the early 19th century. Along with Demetrias and Chalcis, the Acrocorinth during the Hellenistic period formed one of the so-called “Fetters of Greece” – three fortresses garrisoned by the Macedonians to secure their control of the Greek city-states.
Corinth continued to thrive through the Roman period and during the early Christian era. The Apostle Paul visited Corinth in the 1st century CE and established a Christian community there. It was said he arrived in Corinth in 49 or 50 AD and created the first Church of Corinth, where he met Priscilla and Aquila, who became two of the Seventy Disciples.
The city's archaic acropolis was already an easily defensible position due to its geomorphology; it was further heavily fortified during the Byzantine Empire as it became the seat of the strategos of the thema of Hellas and later of the Peloponnese. It was defended against the Crusaders for three years by Leo Sgouros. Afterwards it became a fortress of the Frankish Principality of Achaea, the Venetians, and the Ottoman Turks.
Three circuit walls formed the man-made defense of the hill. The highest peak on the site was home to a temple to Aphrodite. The temple was converted to a church, which in turn was converted to a mosque.
Currently, it is one of the most important medieval castle sites of Greece. The interior contains the ruins of the temple of Aphrodite (5th-4th century BC), the spring of Ano Peirini, several Christian churches, a Byzantine underground cistern, mosques, fountains etc.
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.
