The Holy and Great Monastery of Vatopedi on Mount Athos was built during the second half of the 10th century by three monks, Athanasius, Nicholas, and Antonius, from Adrianople, who were disciples of Athanasius the Athonite.
From then onwards, several buildings have been constructed, most of them were built during the Byzantine period and during the 18th and 19th centuries when the monastery reached its highest peak.
Vatopedi features numerous wings, towers, etc. The katholikon (main church) was built in the tenth century, and is dedicated to the Annunciation of the Blessed Virgin Mary, in accordance with the Athonite architecture. Samples of Byzantine mosaics remain, some of which were retouched in the 12th century and in 1312. Nineteen smaller chapels in addition to the katholikon lie within and outside the boundaries of the monastery. Five are in the katholikon. These of the Saint Nicholas and Saint Demetrios lie left and right of the eso-narthex, and the chapel of the Virgin of Consolation. In the monastery are the chapels of the Holy Girdle and of the Saints Kosmas and Damian.
More than 120 monks live in the monastery today, where extensive construction projects are underway to restore the larger buildings.
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.
