Monument to the Space Conquerors
Built in 1964, this is a great example of a Soviet monument. Gigantic, spectacular and with just a touch of kitsch. In the surrounding park you can see other sculptures of famous astronauts, engineers of major space programs and, of course, Lenin leading the people towards progress. Inside the Monument to Space Conquerors is a museum on the achievements during the time that Russia was the USSR, that I didn't get to, but I'm told it's interesting.
