Castillo de Alcaudete was built by the Arabs over the remains of a previous Roman fortification and taken by the Christians in 1085 during the reign of Alfonso VI. For almost three hundred years thereafter, the castle kept changing hands until 1340 when the Christians took it over.
The design is polygon in shape, adjusted to the terrain escarpments. The structure is surmounted by six towers, including the Tower of Homage, which has a door on the north side, guarded by two additional towers.
Today it has become a tourism-cultural space which houses the Interpretation Centre on the life of the Military Order of Calatrava. Visitors will go back to the 13th century to discover the construction of a castle on the border with the Nasrid Kingdom, the lifestyle and internal structure of the Order, the military armament used for the assault and defence of a fortress.
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.
