The present ruins of the summit castle are located on the summit of the 644 m high Hohenkrähen ("Krayen"), a mountain of volcanic origin north of Singen in the Hegau, between the villages of Duchtlingen, Schlatt unter Krähen and Mühlhausen in the Duchtlingen district.

Steckborn, located on the Swiss side of the Untersee, is one of the beautiful places on the Swiss side that invite with a historic old town. The first written mention of Steckborn can be found in the middle of the 9th century in connection with the island of Reichenau. The first traces of settlement go back to the Neolithic Age. Pile-dwelling settlements were built here as well, as is known from the Überlinger See.
