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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
