St. Nicholas Monastery Complex is situated in the Dnieper river valley, in a fenced territory. It consists of a number of stone buildings: the St. Nicholas and St. Onuphry Churches, a dwelling house (a hospital), a belfry and a fence with an entrance gate.
The stone building of the St. Nicholas Church was erected on the place of a wooden church from 1669 to 1672. The church is a three-nave cross-dome basilica with an octahedral light tambour and a large bulbous cupola over the middle part of the church. The dominant architectural feature of the church was a two-tower main facade with a figured pediment decorated with a set of diversiform tiered bays.
At present the complex is an active monastery. It was added to the UNESCO World Heritage Tentative List in 2004.
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.
