 In 1892 Major Heinrich Steimle examined this in more detail by excavations on behalf of the Empire-Limes-Commission.The Roman military thermal bath, which was also open to the civilian inhabitants of the village was placed outside of the fort and excavated in 1978 north of the fort on a high terrace on the ridge above Remstal.The fort and surrounding remains of the Unterböbingen castrum are since 2005 part of the UNESCO World Heritage, as they are a section of the Upper-Rhaetian Limes.
