Brest, Belarus
As a border town, Brest was often attacked by Yatvyags, Poles, Lithuanians, and Teutonic Knights. The city was the center of the Brest land and one of the most important cities of Kievan Rus and the Galicia-Volyn principality. Brest was considered a "window to Europe" for Russia, a stronghold on the way to Kyiv.
