The Castle of Ayora was built probably in the mid-13th century, after the Reconquista, on the site of an ancient Arabian fort. The architectural ensemble was composed of the four-storey residence-palace, two fortified towns, and one large keep, as well as other rooms for the soldiers and serfdom, aljibes (European Middle Ages castle cisterns that collected the rain water to provide drinking water to the castles) and gardens. This was surrounded by around 1,000 m of defensive walls and defensive towers.
The castle was reduced to ruins by the troops of Philip V of Spain, in the War of the Spanish Succession, but its profile and its vast size are still noticeable. The keep, of square plan, the Puerta Falsa (Fake Door), commissioned by the Marchioness of Cenete in the 16th century on which it was her coat of arms, as well as paintings, defensive walls, buckets, moats, and cisterns, stand out in the remains of the castle.
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.
