the only major property, with 97 "morgen" (somewhat less than 200 000 m²), was the "herrschaftliches höfchen" (“manorial estate”), which passed to "kollegiatsstift st peter und alexander" from noble ownership as a donation in 1334, later being bestowed by the "stift" upon various country noblemen. later still, it passed to the liege lord, the elector of mainz, and eventually – about 1837 – it was sold into private ownership to the landed family heeg. about 1800, the old "hofreith" was torn down, and across the road a major estate with an oil and tobacco mill and a wine press was built, today known as the helmshof.
