The Castle of Archidona was built by the Arabs in the 9th century and rebuilt by Alhamar, the first Nasrid king, in the 13th century. In 1462 Archidona was conquered by the Conde de Osuna, beginning to expand outside the walls to occupy the area it currently has. After the Christian conquest, the new population center and its most prominent urban representation in the Plaza Ochavada, the 18th century curious octagonal shape is established; in her red brick and white lime are combined.
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.
