or PETEVAR, a frontier town of Austria, capital of the Servian Military Frontier, stands on a promontory on the right bank of the Danube, which is here crossed by a bridge of boats, leading to Neusatz on the opposite side, 45 miles N.W. of Belgrade. It is one of the strongest places in the empire both by nature and art, as it occupies a high escarpment rock, washed on three sides by the river, and has two fortresses, the one on the top of the rock, and the other, which incloses the town proper, on a gentle slope to the north. It presents a formidable appearance both from the river and the land, on account of the walls, pierced with port-holes, and the tiers of turf-covered bastions by which it is defended. The town, which consists of one main street, with two others parallel to it, contains an arsenal with many Turkish trophies, the parish church of St George, which has several interesting tombs, and other buildings. The lower fortress has large moats, which can be filled with water from the Danube. Peterwardein is said to derive its name from Peter the Hermit, who marshalled here the army of the First Crusade. The garrison amounts to about 3000 men, though it is capable of being augmented to 10,000. Pop. (exclusive of garrison), about 5000.
