Magnificent Coca Castle was built in the 15th century by Alonso de Fonseca, a mighty archbishop of Seville, during the reign of King Enrique IV of Castile. It's made up of two square baileys separated by a passageway. Both show polygonal towers at the corners. The double walls are 2.5 m thick and it's circled by a deep dry moat.
Coca castle is a mixture of western and Moorish military architecture, as can be seen from its decoration. It has a square ground plan, a moat and two walled enclosures, which gives it the air of impregnability for which it has been known over the centuries. The keep is located in the second area. It is made of brick and its walls are profusely decorated. The interior is very luxurious and lavish, and conserves its Mudejar decoration. Due to its great splendour, it was used more as a palace than as a fortress. It is one of the crowning works of the military Mudejar style.
The castle is owned by the Alva family and now serves as a training center for foresters. Their school is situated in the inner bailey.
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.
