Xativa Castle consists of a twin fortification divided between the older Castillo Menor (minor castle), built on the Iberian and Roman remains of the site, and the more recent Castillo Mayor (main castle), built during the medieval period.
The fortress is strategically located on the ancient roadway Via Augusta leading from Rome across the Pyrenees and down the Mediterranean coast to Cartagena and Cádiz.
The minor castle was originally a Celtiberian stronghold and was then taken by the Carthaginians in the third century BC. It is said to be the place where Hannibal planned the conquest of the Roman city of Saguntum, as well as where his son was born in 218 BC.
In 1092 the castle fell to the Almoravid dynasty who were later pushed out in an uprising that took place in 1145. During this uprising, the castle was besieged by the ruler of Valencia, Marwan Abd-al-Aziz. In 1171, the castle finally joined, along with the rest of the Levante coast, the hands of the Almohads.
King James I of Aragon began his religious conquest there in the summer of 1239, capturing Xátiva in 1244, following a five-month siege. After surrendering to the Christian monarch, avoiding more bloodshed and signing the Treaty of Xàtiva, the Governor handed over the smaller nearby castle to James I, while the moors were allowed to continue occupying the larger castle for another two years, based on the terms of the treaty.
After the two years had elapsed, King James I of Aragon forcibly repopulated a large part of the town with Catalan and Aragonese settlers, meanwhile slaughtering and expelling a portion of the Muslim and Jewish populations from the city. In the subsequent decades, many Mudéjar (Muslims living under Christian rule after the Reconquista) left the region for Granada or North Africa.
The castle once again saw fighting during the war of the Spanish succession, as Castilan and French troops beat Aragonese and English troops that had taken refuge in the fortress during the siege of Xàtiva, in 1707. The site was later seriously damaged in the 1748 earthquake that rocked the region, and it lost its strategic importance.
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.
