Saint Nicholas Church is mentioned in document for the first time in 1387. In 1901-39 the Church of St. Nicholas was the only church in Vilnius where the mass was held in Lithuanian. By the same token it was a centre of Lithuanian culture (its famous dean Kristupas Čibiras was killed in 1942 during a bombing raid).
After the World War II, the Cathedral of Vilnius was closed and the Curia of the Archdiocese of Vilnius was moved to the St. Nicholas Parish building and the Church of St. Nicholas in fact performed the functions of a cathedral.
During the Soviet occupation a statue of the patron of Vilnius, St. Christopher, was erected in the church orchard (sculptor Antanas Kmieliauskas, 1959); it was an obvious act of resistance, as the city's coat-of-arms with St. Christopher's figure was banned at that time.
Archaeologists believe that the original church survived till the present day. Externally, the church represents the Brick Gothic style, while its interior has been renovated several times. The church belfry was built in the 17th century in the Baroque style. Its façade is flanked by two stocky buttresses with cut-off tops. The triangular pediment with niches has been recently renovated accentuating its original Gothic character. In the interior, four elegant octahedral pillars support web and star vaults. The high altar holds a painting of St. Nicholas with a silver setting from the 16th century. The church is adorned with two sculptures: a polychrome statue of St. Louis from the Gothic period, and Vytautas' bronze bust erected in 1930 (sculptor Rapolas Jakimavičius).
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.
