If you should mention one national icon for Belarus, the Brest Fortress should be it. The grey concrete main entrance with the star-shaped opening is on the 50 BYR note, while the other side of the bill has the south entrance depicted. The fortress was originally built in the 19th century in what was then part of the Russian Empire. It was one of largest of the Russian fortresses, but became even bigger with every modernizing and upgrade it went through. During WWII, the Soviet soldiers defended the fortress so hard against the Nazis that Brest became one of the 11 "Hero Cities" in the Soviet Union along with Leningrad and Stalingrad. Today there isn't much left of the fortress besides the outer wall, which is riddled with bullet holes, and some buildings including a gorgeous Byzantine church. But, considering how heavily it was bombarded, it's impressive that there is anything left at all. The main sights are a towering obelisk and a giant stone face. The internal fame at the base is occasionally guarded by teenage soldiers with guns, who put on a show at the guard shift.
