The Moorish fortress or Alcazar of Carmona rises above the Puerta de Sevilla (Gate of Seville), forming an almost impregnable defensive complex. It underwent major alterations in the 14th and 15th centuries. Theestoration work carried out between 1973 and 1975 included the refurbishing of several sections as venues for staging cultural events.
Puerta de Sevilla origin dates back to the 9th century BC. The Carthaginians created the first layout, of heavy rectangular appearance, and made it their bastion against the Romans. The Romans reinforced and restored the structure with a set of gates which is still preserved. Many interventions were carried out from the 12th century onwards.
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.
