San Marcos Castle is a 12th-century fortress, commissioned by Alfonso X 'The Wise' upon the remains of a Moorish mosque on the banks of Guadalete River. Despite being so old (800 years), the castle is preserved in perfect conditions of use. Cultural events, conferences, lunches or dinners can be held both inside or outside in the garden, for up to 300 people.
The inside of the old mosque is an ideal place for events and closing dinners for conferences and conventions, because of its historic atmosphere. During the summer, the area around the fortress is an incomparable venue for celebrating open-air events.
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.
