Bač, a historical place after which the entire extensive geographical region between the rivers Danube and Tisa was named Bačka, is located at 450 23' 31'' N and 190 52' 57'' W. The town spreads out across an alluvial terrace that has an elevation of 79-85 m (above the mean sea level). A navigable Karavukovo-Bački Petrovac canal cuts through the area, being a part of the Danube-Tisa-Danube hydro system. Bač is 61 km away from Novi Sad, 141 km from Belgrade and 300km from Budapest. Bač is the center of a municipality that bears the same name, bounded by the Danube river on the west, which, at the same time, represents a natural state border with the Republic of Croatia.

3. Image of medieval surrounding of the fortified town of Bač formed trough archaeological excavations
Image of medieval surrounding of the fortified town of Bač, formed trough archaeological excavations, indicates that Bač had positive predisposition to become the core of a megalopolis during the Middle Ages. Locations of medieval settlements that are contemporary of the fortified town demonstrate correlation. Settlements were located along roads, but other possibility is that roads were defined by the positions of settlements. Most settlements were established on the banks of the Mostonga river and other smaller river flows in the area. Those settlements were forming a wider zone, bounded by the Danube river on the west. People who used to live within this area, enclosed by the Danube river, other smaller water flows and the Mostonga river, did not seize an opportunity to further develop this already built up and well connected area, due to unfavorable historical circumstances. If they had, today we would only rarely find a traces of the big medieval city under the radial boulevards connecting the Danube shore/port with the center of the Bač megalopolis.
