In 1552, during the Second Margrave War the castle fell unopposed into the hand of the Margrave of Ansbach. In August that year, troops from Ulm retook the castle after several days of shelling with heavy stone cannon balls. Having lost its significance and value as a fortification, the city of Ulm started to demolish the castle starting in 1552, sending all usable materials to Ulm. The ruins were left and the site became overgrown over the following centuries. Starting in 1932, the site of Helfenstein Castle was excavated with the help of Army engineer troops. A south tower was rebuilt and stairs and wooden bridges were erected to allow easy access from several directions. The ruined complex is a favorite destination for weekend walks and excursions."@en .
