From Wikipedia:
The Naval cathedral of Saint Nicholas in Kronstadt is a Russian Orthodox cathedral built in 1903–1913
as the main temple of the Baltic Fleet and dedicated to all fallen seamen.
The cathedral was closed in 1929, and was converted to a cinema, a House of Officers (1939)
and a museum of the Navy (1980).
Today it is a church again, being restored. The restoration program will be completed by Summer 2012.
