Originally dating back to the middle of the 14th century, this odd-looking church which also functions as the city’s Russian Orthodox Cathedral owes much of its partial Neo-Byzantine design to reconstruction work completed in 1522. In 1808 the building fell into the hands of Vilnius University who divided it into two floors, constructing a library, classrooms and dissection rooms for anatomy classes inside. In 1842 soldiers moved in as the church acted as a barracks before it took on several other uses until General Muravyov and his brother had it restored to its current Georgian appearance and used as a house of worship towards the end of the 1860s.
