The Castle of Santa Àgueda is situated over an elongated plateau. The castle is accessed by an ancient Roman road. Next to the castle there was also, until recently, a chapel dedicated to Saint Agatha.
The castle was built over an ancient Roman castra by the Arabs, when Menorca was part of the Caliphate of Cordoba. The exact date of its construction is not known, but it was prior to 1232. In 1287, it became the last standpoint of resistance by the Arab inhabitants when the island was invaded by King Alfonso III of Aragon. The castle was later destroyed by Alfonso's grand-nephew King Peter IV of Aragon around 1343.
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.
