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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
