First built in the 13th century, but thoroughly altered in the 15th century, Ampudia Castle has a square plan with a gothic central courtyard and 4 towers on each corner. Half of the castle complex is surrounded by a barbican defended by cylindrical towers.
It belonged to different owners such as Juan Alfonso de Alburquerque, Sancho de Rojas and Pedro Garcia Herrera (Marsical of Castille) among others.
In 1521 it was assaulted and occupied by the Comuneros (Castillan independentists who fought against Charles I of Spain) headed by the belicious bishop Acuna. It was later retaken for the Crown by the Duke of Lerma.
Today Ampudia Castle is a private property, but its grounded departments can be visited on a guided tour. Other parts of the castle like the upper levels or the keep are not open for visit.
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.
