San Benito de Alcántara is a monastery in Alcántara. After the Christian conquest of Alcántara in 1213, the city was given to the military Order of Calatrava four years later. In 1218, they in turn ceded it to the order of San Julián de Pereiro, which changed its name to that of the military Order of Alcántara. In 1488, the order's council decided to build a new monastery in the city. Construction began in 1505 and lasted for most of the 16th century. The order's main architect, Pedro de Ybarra, worked on the design.
In 1706, it was sacked during the War of Spanish Succession, and it was damaged by the 1755 Lisbon earthquake. In 1835, it was abandoned and began to fall into ruin. Later it was acquired by Hidroeléctrica Española, which restored it and occupied the structure until 1966. In 1985 it went to the Fundación San Benito de Alcántara.
The exterior's main feature are the three apses (the central polygonal and the side ones semicircular), characterized by large coat of arms. Opposite a three-storey loggia with Renaissance arches, a semicircular auditorium has been built; the classical theatre festival of Alcantara is held here in the summer.
The interior has a nave and two aisles. The cloister, in Gothic-style, has a square plan with two floors. It was built atop an Moorish fortress.
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.
