The Great Patriotic War

Strangely, I don't have a good close-up photo of the museum of the Second World War, or in Russian, the Great Patriotic War. Equally bizarrely, it was the ugliest building in town, not a Stalin-baroque palace, but a brutalist concrete pile, on October Square.

But it is important. Belarus lost 1/3rd of it's population in the war (the Eastern front basically running right through it, both it's Jewish population and pretty much everyone else were extremely hard hit in first German occupation and then war). In Minsk, 5 buildings remained in 1945.
