Heraclea was an ancient city of Magna Graecia. The ruins of the city are located in the modern comune of Policoro in Basilicata. It was a Greek colony, but founded at a period considerably later than most of the other Greek cities in this part of Italy. The foundation of the city is placed by Diodorus in 432 BCE. It became famous as the site of the first major battle of the Pyrrhic War in 280 BCE in which king Pyrrhus of Epirus defeated a Roman army on the head of a coalition of Southern Italian Greek city states.
The Clementinum is a historic complex of buildings in Prague.

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.
