Interesting history, this one has

So...here you see St. Casimir's...Vilnius' oldest Baroque Church built in the early 1600's. It began as a Jesuit church and then, under Czarist ruling, was converted to a Russian Orthodox church (an onion dome was added to the top center of church). Then, under Soviet ruling, was converted to an atheist museum (the onion dome was removed from the top center). Now, as a result of Lithuania's recent independence, it has been returned to Jesuit monks.
