The Vieux-Port (Old Harbour), is at the heart of La Rochelle. Enclosed by its mighty medieval towers (Saint Nicolas and La Chaîne), the picturesque harbour is now lined with seafood restaurants and bars.
Since the 13th century, the port of La Rochelle has occupied this site. It is likely that from the beginning it was fortified. The remaining towers date from the 14th and 15th centuries. They survived the destruction of the enclosure after the siege of 1628. On each side of the entrance, the Saint Nicolas tower, the highest, and the La Chaîne, and further on, linked to the latter by a curtain wall, the Lantern tower, both a lighthouse and a prison.
References: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.
