The Dymaean Wall (Teichos Dymaiōn) or Kalogria Castle is a prehistoric acropolis in western Achaea, Greece. The fortress stands in a strategic position on a rocky hilltop, north of the Prokopos lagoon, near the village of Araxos. It was built in the Mycenaean period, probably around 1300 BC, but human occupation of the site started already around 3500 BC. It was deserted in the 18th century AD. During World War II it was used by occupying Italian forces, who built a number of military installations on the site and damaged the prehistoric fortifications.
It was named the Dymaean Wall after the nearby ancient city of Dyme. During the war between the Achaean and the Aetolian Leagues (220–217 BC) it was seized by king Philip V of Macedon.

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.
