Burg Gebsenstein

Burg Gebsenstein occupies a two-part defensive position on a northwest-facing spur on the northeast flank of the Heilsberg, covering roughly nine hundred square metres at about five hundred and fifty metres above sea level and lying nearly one and a half kilometres south of Hilzingen church. The layout uses the natural rock of the spur together with earthworks to form a compact hilltop stronghold and an adjacent lower, defended area.

The core hilltop platform measures about twenty-three by sixteen metres and drops away steeply to the north over exposed rock. Around the edge of this plateau an embankment survives that is interpreted as the remains of a former curtain or ring wall. Deep hollows up to four metres in the centre of the plateau have been recorded; these are regarded as traces of cellars once belonging to buildings on the summit, although they have also been considered possible recent extraction pits. These summit features survive in a fragmentary state.

On the south and east faces, roughly five metres below the main plateau, a terrace about three metres wide runs around the slope and helps define the protected core. At the foot of the hill a continuous trench encircles the spur on all sides except the steep northern face. This surrounding trench reaches widths of up to sixteen metres and depths of three to four metres where it is best preserved, while the west side shows partial silting. Beyond the trench on the eastern and southern approaches a low outer bank about forty centimetres high remains.

South of the core the outer bank leads into an intentionally steepened slope that continues to a transverse cutting at the tip of the spur. That cutting runs roughly south to north and measures about two metres deep on the outer face and three to four metres deep on the inner face, forming a further defensive obstacle across the descent. West of the summit an enclosed area approximately thirty to thirty-five metres long and ten to twenty metres wide has been identified as the probable site of the outer bailey, where the castle’s economic buildings would once have stood. The northern edge of this outer area is closed by a narrow rock ridge about three metres across and one metre high.

A nearby secondary high point on the Heilsberg rises to about five hundred sixty-one metres above sea level. Historical commentary records that excavations around 1800 at the castle site produced a small golden vessel attributed to a Herrn von Raiser; that find was reported in a published note, the exact identity of the named person was suggested to be Johann Nepomuk von Raiser, and the object’s current whereabouts are unknown.
