Deggenhausertal itself is a part of the district Bodenseekreis which is on the north shore of Lake Constanz.

Deggenhausen is located in valley, alongside the small river of the Deggenhauser Ach, about 8 km east southeast of Heiligenberg.

Located northeast of the village was an eponymous castle, the ancestral home of the House of Deggenhausen which has been attested to the period 1137–1314.

After the Deggenhausen family became extinct, the region passed to the Lords of Markdorf, who later sold it to the Prince-Bishopric of Constance.

[1] After the extinction of the line Werdenberg-Heiligenberg-Sigmaringen-Trochtelfingen in 1534, Deggenhausen passed to the Counts of Fürstenberg.
