Sarskoye Gorodishche or Sarsky fort (Russian: Сарское городище, literally "Citadel on the Sara") was a medieval fortified settlement in present-day Yaroslavl Oblast, Russia. It was situated on the bank of the Sara River, a short distance from Lake Nero, to the south of modern Rostov, of which it seems to have been the early medieval predecessor.
