St. Nicholas Church in Lithuanian, sv. Baznycia Mikalojaus, is the oldest church in Lithuania, built in the old town of Vilnius in the 14th century. It's mentioned in writings for the first time in 1387. Archaeologists believe that it's the same Catholic Church that has survived until today. The exterior is brick Gothic style, while the interior has been renovated several times. The Baroque steeple was built in the 17th century.
A baroque Catholic church, considered a masterpiece and one of the few remaining buildings of this type left standing during the Soviet era - most became museums or factories. Inside you can see 2000 figures in stucco.
It is an orthodox church. You can't take pictures during the ceremony, and if you don't put your hands in your pockets during the collection, it will attract attention. But it's worth going in to see, as it's full of colour and detail.
