This lordly estate was what was actually mentioned by name in the first documentary mention in 1285. In a dispute between the Provost of Ravengiersburg and the "Vögte" of Heinzenberg in that year, it was determined that the monastery should own its four lordly estates free of all service. The estate at that time had a manor house, two barns, a stable and a mill. The grounds amounted to 44 "Morgen" (roughly 14 ha) in cropfields, a great heath field in the Oberbrühl of 12 "Morgen" (about 3.8 ha) and 11 meadows, along with a forest of 200 "Morgen" (roughly 64 ha).
