Medinaceli Castle was built in the 9th century and rebuilt in the 15th century. There aren’t many remains left of this castle which was of great importance during the Middle Ages. According to legends, inside the castle, which is now completely restored, there was an Arabic citadel where Al-Mansur was buried after being defeated and killed in the Battle of Calatañazor in 1002, although, there aren’t any remains of this citadel.
The strategic situation of Medinaceli, in the middle of the Jalón River valley, the natural passageway between Aragon and the Castilian Plateau, turned it into a key battleground between Muslims and Christians. Legend has it that Al-Mansur, the “Invincible” died here and was buried “in the depths of hell”. El Cid took over the city, which was under Muslim domain, and was lucky enough that there was an exceptional chronicler that immortalised him in art form. According to Menéndez Vidal, one of the minstrels of Cantar del Mío Cid was from Medinaceli or from this region.
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.
