See the center of minsk! October Square is huge, has lots of history, and is worth checking out! Apparently they found skeletons belonging to mammoths (although I am not sure how true this rumor is) when they were excavating the ground under it.
If you like big squares, plus it has the center of minsk there
Also check out the buildings nearby: Palace of Culture of Trade Unions and Minsk Palace of Republic
