Santa María da Armenteira Monastery belongs to the Cistercian order and was founded by the knight Ero de Armenteira in 1168. It has a square cloister, a kitchen, and a tower, all in the 18th-century Baroque style. The monastery was abandoned after the sale of church lands in 1835. The church has a floor plan in the shape of a Latin cross, three naves and three semicircular apses. The central nave is crowned with a pointed barrel vault, and the side naves with groin vaults. The transept has a vault raised on Mudéjar-style pedentives. On the façade, the 12th-century rose window is of particular interest. The whole complex has today been rebuilt thanks to the Association of Friends of the Monastery of Armenteira.
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.
