Castillejo de Robledo castle and its lands were property of the Order of Malta until it was suppressed by Pope Clement V in 1311. After that the estate passed to the Knights Hospitaller and then to the residents of the town. In the town there was an old Moorish fortification where the current castle was built in the 12th century. The remains of the original wall are visible and are characterized by a greater thickness than the walls erected later.
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.
