Chirel Castle had an Muslim origin. The current castle was built after the Christian Conquest, which took place in the thirteenth century, when the Moors were expelled.
During this time, the fortress of Chirel was used by the Christians as a base of operations, under the command of the king of Aragon, James I the Conqueror, since they were at war with the Muslim leader al-Azraq.
Around the year 1748, a natural catastrophe occurred, an earthquake of great magnitude that ended up collapsing an important part of the fortress.
Today, Chirel Castle is on the waiting list to be rebuilt. In any case, it is an ideal place to visit, since, although they have not repaired their structures, they have done so with the roads that lead to the castle, so that it is a safe place, away from possible collapses, and a great tourist attraction.
If we go today to the Castle of Chirel, we will find an important part of its Main Tower, its double wall and two other large towers, and, also, a large cistern, which is still standing. In addition, you can contemplate the impressive view of the Cinto del Castillo annex, the Cintos de Sácaras annex and the Cerrador, and the Cortes reservoir.
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.
