In 1718, on the Elector's orders, all land was measured, and the information yielded by this survey was compiled into a "Grund- und Extraktbuch", a catalogue not only of land measurements, but also ownership. Non-resident owners at this time were Himmerod Abbey, Stuben Monastery, Sieburg Monastery, the Foundation at Pfalzel (nowadays an outlying centre of Trier) and the virgins’ convent at Karden. Hunting rights were held by the Lords of Metternich-Winneburg, as were fishing rights on the Ellerbach, although these were actually jointly held with the Elector of Trier. The monastic institutions were later stripped of their landholdings in 1794 when the French Revolutionary occupation began.
