Schwanberg is a mountain, or hill of higher elevation (474 m), in the rural district of Kitzingen, Regierungsbezirk Lower Franconia, Bavaria, Germany. It is part of the Steigerwald. In ancient times the mountain was used by the Celts as a refuge. It is probably safe to assume that the mountain has been considered sacred ground since. Later, the counts of Castell build a castle that still exists today. The southern slopes are used for viniculture; the top of the mountain is covered by forest. Parts of the region belonged to the county of Castell.
