Monastery of Santa María de Oseira became a monastery of the Cistercian order in 1141, an order of French monks sent by Saint Bernard of Clairvaux. The monks left in 1835 forced to leave by the government policies, abandoning it. They returned in 1929, this time being a community of Cistercians of the Strict Reform - commonly called Trappists. The monastery is popular stopping point on the pilgrimage to Santiago de Compostella.
The church was built between c.1200 and c.1239 AD. It is considered a landmark of Romanesque architecture in the Spanish peninsula. Its design was inspired by other pilgrimage churches. The main chamber is known as the 'palm tree room' and boasts a dome which is supported by four columns. It also possesses a Lapidarium: a collection of stone pieces obtained during the restorations and excavations. The buildings are in process of restoration by the state & monastic community. The monastery is a major state monument, and open to visitors.
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.
