According to legend, Pontivy was founded in 685 AD by an English monk called Ivy who built a wooden bridge across the Blavet, giving the town its name – Pont d’Ivy. The town really began to develop in the 12th century when Viscount Rohan settled there and in the 14th century it became the political and administrative capital of the viscounty.
The main site in Pontivy is its château, which overlooks the River Blavet a short walk from the town centre. The present castle was built in 1485 by Viscount Rohan, whose aristocratic line dates back to 1120. The Rohan family seat has seen plenty of action during its 500-year history including being besieged during the Duchy of Brittany War of Independence in 1488 and taken over by Catholic forces during the French Wars of Religion in 1589. The château, which retains many original features, is open to the public and often stages art exhibitions.

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.
