The old Cistercian monastery of Melón contains in its church one of the largest and most imposing sanctuaries in Galician monastic architecture. It was founded by monks from Clairvaux Abbey in France, in 1142. It was once very powerful, as attested by the remaining architecture.
Various rooms in the monastery, the galleries in the cloister and the two later chapels are currently undergoing restoration, as well as the entrance to the monastic site.
The only element remaining from the primitive Romanesque church with three naves is one section of a nave, the transepts with two semicircular chapels, and an interesting ambulatory with freestanding columns. Its walls and roofs were refurbished once again in the late 19th century in the historicist style. It is topped with cross and quarter-sphere vaults, and has a rectangular tower at the point where the transept meets the naves.
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.
