These hills form the Fruška-Gora notable for their vineyards, the produce of which makes the famous Karlowitz wine. While on the left side the country continues flat, on the right are low cliffs. Ujlak (Ilok), on a rocky height, one of the most picturesquely situated places along this part of the river, is interesting as being on the site of the Roman Cuctium, and possessing remains of that distant past. Since then it has been occupied by the Quadii, the Magyars, and the Turks. In the monastery here lived the warrior-monk, John Capistran, who fought under the banner of John Hunyadi at the siege of Belgrade; here, too, he was buried, “his body being lowered into an almost bottomless well by the monks, in order that his remains might never, in any future incursions of the Turks, be disturbed and dishonoured by his enemies the infidels.” Opposite, on the left bank, is Palánka. As the river nears the foot of the hills on the right, the scenery becomes more attractive and more varied. Soon is seen ahead the famous fortress of Pétervárad (Peterwardein). After passing Kamenitz on the right, we soon reach Ujvidek (Neusatz), a large and pleasant old town, which is an important centre of the Alföld trade. Here the Danube has turned northerly to sweep round the little peninsula on which stands the fortress that has for some time formed a notable object in the view. Here the Danube is crossed by a bridge of boats (eight hundred feet long), such as was, well on into the nineteenth century, the ordinary means of communication between towns on opposite sides of the river. Pétervárad (Peterwardein) which, from its situation, has been dubbed the Gibraltar of the Danube, consists of a large fortress on a rock about two hundred feet above the river, with a small town below it. It owes its importance to its strong, isolated situation and its position at the end of the old military frontier established or revived by “King” Maria Theresa, a frontier tract, all the male population of which had for three weeks out of every month to take military duty in guarding the land from any attack on the part of Turkish neighbours. The town owes its present name--it is believed to have been the Acuminicum of the Romans--to the fact that it was here that Peter the Hermit marshalled the people whom he had gathered together in 1096 to take part in the first of the Crusades. The picturesque story which tells of Peter wandering through Europe riding on an ass and preaching the Crusade--as being, indeed, the originator of the great religious movement of the Middle Ages--is doubted by modern historians, but it is one that tradition will not willingly let die.
