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.
