Fort Louvois was built between 1691 and 1694, during the reign of Louis XIV, on the Chapus islet, and is about 400 metres offshore in the town of Bourcefranc-le-Chapus in the department of Charente-Maritime. The fort sits opposite the citadel of Château d'Oléron on the island of Oléron. The fort was positioned so that a crossfire from the château and the fort would control the Pertuis de Maumusson (Passage of Maumusson) and impede access to the Rochefort roads from the south.
In 1755 Fort Louvois saw modifications that were intended to keep pace with advances in weaponry. One result was the reduction in the number of embrasures for artillery to ten from the original 16. The battery lost its roof, and the fort also received latrines on the walls. These were the last modifications to the fort.
In 1824 the fort was armed with four 24-pounder guns and three 32-pounder mortars. Then in 1870 it received six 22-pounder howitzers. The fort was repaired in 1875 to undo damage from the action of the sea. At that time it received a telegraph station and six 16-pounder guns.
After the First World War, the French military abandoned the fort. Fort Louvois only saw action towards the end of World War II when bombardment greatly damaged the fort, necessitating later restoration.
Since 1972 the fort has been the site of a museum of oyster farming, and there are oyster beds next to the causeway that joins the fort to the shore. The fort also houses a permanent exhibition that describes the history of the fort and that contains models of fortifications on the Charente coast. During the summer a shuttle boat that operates during high tide takes visitors to the fort; at low tide the fort is accessible via a causeway.
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.
