Castillo de Bujalance was built in the 10th century during the Caliphate of Abd-ar-Rahman III. It is a clear example of Muslim military architecture in Al-Andalus. It subsequently underwent several modernizations, most recently in 1512, which were paid for by Queen Joanna of Castile.
It is rectangular in shape, measuring 59 metres north-south and 51 metres east-west. The castle's original name, 'tower of the snake', and the fact that it had seven towers, led to the current name of the city and its coat of arms. In 1963, the Ministry of Culture declared the site a Bien de Interés Cultural monument. Currently, its courtyard is used as a cultural space, which is in the process of being cataloging, restored and reconstructed. Highlights include the Festival of Theatre, Music and Dance (Nights at the Citadel) and Andalusian Dinner during the summer months.
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.
