Brno is the capital of South Moravia and the second largest city of the Czech Republic. It is very nice city with very nice people. Well, maybe Prague is more impressive architecturally, but Brno has gorgeous historic center and castle (Špilberk) too, plus a lot of wineyards and traditional wine cellars.
Simply… if you visit Czech Republic, do not miss Brno :D.
