The Casa Fuerte de la Cruceta was finished in 1773 for the purpose of housing cavalry units. The fortress was one of the westernmost defensive positions built in the 18th century by King Charles III of Spain to defend the area of Almería and the Cabo de Gata. It was originally intended to house soldiers who were tasked with guarding the areas between Torre García and Perdigal. The King approved plans for its construction in 1771 and works were completed in 1773. In 1778 the fort had a permanent garrison of 14 soldiers.
By 1830, the fort was abandoned by the army but in 1857, it was transferred to the control of the Carabineros. In 1941, the fort was garrisoned by the Guardia Civil.
The fortress was restored in 2005 and is accessible as a part of the waterfront of El Toyo.
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.
