In 1322, the domain excluding the castle was sold in 1322 by Wilhelm von Herteveld to Graf Dietrich VII of Cleves.
Facing financial difficulties, Elbert in turn passed it to his relative Jobst Gerhard von Hertefeld, thereby reunifying the property of the two branches.
The hartefeld properties had by this time become quite extensive, incorporating not just Uedam and Weeze but also Boetzelaer castle, Hoennepel, Kervenheim and Zelhem (today part of Bronckhorst).
Alexandrine's son Philipp zu Eulenburg became a personal friend of Wilhelm II, who raised him in 1900 to the rank of Furst.
The estate complex today (which is legally preserved as a historic monument), consists of the partially renovated castle ruins, the well-preserved Renteigebäude, and the keepers' lodges, together with a park of roughly 5 hectares.
The predecessor of today's castle, in all probability am inhabited tower or fortified house, dates from the fourteenth century.
The current building acquired its basic form through the reconstruction and extensions of Samuel von und zu Herteveld.
The building acquired steam heating, the gate tower a stoop, and on the north side of the park two watchtowers were constructed.
The park was laid out anew in English landscape style on the foundations of the old moats (some of which had already been filled in the early 19th century.)
The central portion of the building and the historic main tower were recreated, and in April 2005 the tower was given a replica of its original Baroque cap, based on a 1734 drawing by Jan de Beijer, which was fashioned from some ten tonnes of oak, and a 280 kg bronze bell, inscribed with the Hertefeld arms, the year 2004, and the motto Gottes Wort bleibt ewig (The word of God remains eternally).
