The Knights from the Order of Santiago built the Hornos Castle between the late 13th century and early 14th century. They built iton top of an old Arab defensive structure in a strategic location, on one of the roads between the mountain chains of Cazorla and Segura.
Hornos Castle is made up of a defensive site with an outdoor enclosure in the shape of a trapezoid. We can find a large keep, a well right in the parade ground and remains of three turrets.
The keep is 9 metres tall and it has a square base. It was built using masonry with rounded corners, and this feature makes it less vulnerable to the effects of weapons.
The enclosure was also built in masonry. The Almohads builtthree slim towers with small bases,the towers are reinforced with a lining of masonry. Inside the enclosure we find a well of Arab origin.
These days in the Castle we find the Cosmolarium, an astronomical centre and planetarium where films are shown.
The Muslims founded Hornos fortress in the 9th century, and many of its remains such as the well in the parade ground and the three towers date from the Almohad period.
Don Pedro Pérez Pelayo Correa, grand master of the Order of Santiago, conquered Hornos in 1239. Thus, the town was attached to the Encomienda de Segura de la Sierra (a vast territory that belonged to the Order of Santiago).
During the 15th century, the towns of Hornos and Segura de la Sierra played adecisiverole in the political ambitions of the Manrique family who confrontedKing John II and King Henry IV.
Hornos remained part of the territory ruled by the Order of Santiago during the Modern Era, although between 1507 and 1748 the town belonged to the Kingdom of Murcia.
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.
