Burg Immendingen

Burg Immendingen once stood on the southern slope of the Höwenegg hill, 400 metres south-west of the ruins of Hewenegg and about 2.9 kilometres south of Immendingen village in the Tuttlingen district. Built in the 13th century, it was a small medieval stronghold linked to the larger Hewenegg castle nearby. After 1917 the site was turned into a quarry, and the last remains were removed. The archaeologist Konrad Albert Koch recorded its layout before the stone was taken away. A rectangular main castle measured twenty by twenty-four metres, with a trapezoidal outer ward of fifteen hundred square metres. The inner core, four hundred square metres in size, had rounded and rectangular corners and walls two to 2.8 metres thick. A steep natural drop guarded the south, while a ditch and outer rampart defended the north-west side. Visitors today find a quiet hillside where only the old names on maps recall the vanished walls. The Hewenegg ruins stand a few hundred metres away, offering a wider view across the countryside. The gentle slope and open fields make the walk a peaceful one, with no trace left of the former stone buildings.
