Castel d'Ario Castle was a strategic element of a defensive system into the Mantuan territory, together with Castelbelforte and Villimpenta Castles, placed on the borderline with Veneto.
Castel D'Ario Castle represents one of the main medieval fenced-in castles with a pentagonal shape. Five towers are visible, included that one at the entrance, where people can still see the location where there was a portcullis and the ruins of the opposite ravelin. A significant restoration of the praetorian Palace at the end of the 20th century has brought to life frescos at the walls of the first floor, with the escutcheons of the Scaligeris, the lords from Verona, owners of the Castle for twenty years in the second half of the 14th century.
One of the towers inside the castle is called Torre della Fame; the tower was called like this because in the middle of the 19th century some skeletons were found out in this place; probably they belonged to members of Pico della Mirandola and Bonacolsi families, locked up and starved here. A headstone on the castle door reminds to this event.
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.
