The archaeological remains found near the Águila Castle seem to confirm the presence of a pre-islamic population, maybe from the Roman Age.
Apparently in 914 the inhabitants of the fort looked like emirales troops burned the city of Algeciras ships that supported the revolt on Ibn Umar Hafsun, in any case the construction of the castle had to be early to be this hard hit area by Berber rebellions and Mozarabic.
The castle was restored in 1839 after it was conquered by French army in 1810. It was however badly damaged in the explosion in 1842.
The Águila Castle is the most representative monument in Gaucin, from the fortress you can see stunning views, in a clear day you can even see the North of Africa.
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.
