The still easily visible burgstall lies in the parish of Kluftern in the borough of Friedrichshafen in the county of Bodenseekreis in the German state of Baden-Württemberg.

[1][2] The main area of the castle measures about 20 by 21 metres and is surrounded today by an easily recognisable, circular ditch, whose outer boundary is marked by an outer rampart or embankment (Wallrippe).

On the steep eastern hillside, the circular ditch transitions directly into the slope; on the other sides, the remnants of an outer bank can still be made out.

Local accounts locate the story of Christoph von Schmid's Rosa von Tannenburg (the Old Castle representing the Tannenburg) and the demolished New Castle (Fichtenburg) in Raderach.

As a result there is a road called the Fichtenburgstraße in Raderach and a Tannenburgstraße in nearby Unterraderach.
