Mamer Castle is the town hall for the commune of Mamer, in south-western Luxembourg. It is made up of four buildings, set in recently landscaped surroundings. At the main entrance, there is a sculpture of Nicolas Frantz, two-time Tour de France winner, and Josy Barthel, Luxembourg's only Olympic gold medallist, both of whom were born in Mamer.
A castle was originally built in Mamer in the 10th century. By the French Revolutionary Wars, it had fallen into ruin, and was seized and sold off by the occupying French forces in 1798 to Thierry de Bastogne. Police chief Frederic François built a new castle on the site in 1830, surrounded by a 2-metre high wall. It passed hands to Jacques Fischer and Julie Kremer in 1934.
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.
