In an archaeological excavation and documentation carried out from autumn 1880 to autumn 1881 , it was dated to around 300 AD because of a copper coin of Emperor Valerian (reign 253–260 AD). Among other things, cellars, a courtyard, a pistrinum (grinding mill room ) with a millstone made of Eifel lava , a kitchen (room I), a bathing system with hypocaust and drainage ducts with a lead pipe were proven. The Propsteier Villa was found by chance in the summer of 1876. The hill there was popularly called the “Teufelsburg” in the Eschweiler district of Röhe .
