Building located at Condette, the castle of Hardelot is a manor house remodeled in the 19th century in the neo Tudor style, on foundations from the first half of the 13th century.
The first castle at this site was built in the 12th century by the Counts of Boulogne. The curtain walls date back to that time. The present castle was built by Philip I, Count of Boulogne and son of Philip II of France, in 1222. He also built Boulogne-sur-Mer Castle to a rather similiar plan; a more or less circular castle with projecting circular towers but no keep.
In 1848 Hardelot Castle was bought by the Englishman Sir John Hare. He rebuilt one of the best remaining towers into a Tudor-style mansion. Large receptions were given here and the writer Charles Dickens, a friend of Hare, often visited the castle.
Located on the edge of the regional nature reserve of the Condette marsh, near the forest and the dunes of Ecault, it now houses the Cultural Center of the Entente Cordiale, managed by the Department of Pas-de-Calais. The rooms of the castle are fully furnished and retrace the tumultuous relations between France and Great Britain.
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.
