The Château du Haut-Ribeaupierre is one of three castles (with the Château de Saint-Ulrich and the Château du Girsberg) which overlook the municipality of Ribeauvillé. Château du Haut-Ribeaupierre is the oldest of the Ribeaupierre's castles, its existence being known from 1084. It was constructed on an ancient Roman site. Then known as the 'Altenkastel', it was Anselme de Ribeaupierre who took possession of the castle in 1288.
Around 1368, Brunon de Ribeaupierre became owner. Dedicated to a ferocious hatred for the English, he imprisoned Sir John Harleston, who had an imperial safe conduct, in the keep from 1384 to 1387. He was only freed with the payment of a large ransom and after pressure from the Holy Roman Empire. At the end of the 13th century, the castle became a residence of the Ribeaupierres. Another noted prisoner was held in the keep in 1477. Philippe de Croy, Count of Chimay, ally of Charles the Bold, was captured by a Ribeaupierre at Nancy.
Most of the castle today is completely ruined and surrounded by dense vegetation.
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.
