bewingen is gerolstein's northernmost outlying centre, or "stadtteil", located three kilometres (about 1.86 miles) from the town center. here, the kyll river flows in a great arc around the mighty dolomite and basalt massif that juts out from the west, eastwards. the valley narrows and there is only enough room for the railway line, a field road, and the river itself. the road finds its way to gerolstein over the bewinger höhe (heights), thus shortening the way to the nearby middle centre. the local lay of the land was brought about by volcanic activity that created two volcanic peaks—the kasselburg massif, with the burlich and the hahn ("cock") on the kyll river's west bank, and the rockeskyller kopf on the east—whose volcanic minerals and deposits of lava, ash, and cinders during the quaternary period narrowed the river valley.
