In 1647, Adam Vogt von Elspe built a new house, today the east wing of the castle, IN GREAT WAR AND STRIFE AND REPULSIVENESS, as inscribed on a stone, referring to the Thirty Years' War that ravaged Westphalia at this time.

1856 he married his cousin Bertha von Plettenberg-Heeren (* 1832, † 1900), owner of the etates Heeren, Hilbeck, Werve and Hahnen.
After World War II Haus Bamenohl served as accommodation for refugees from the former eastern territories of Germany, later it was converted into a nursing home, leaving a run-down building in 1967 when it closed.
After a vacancy of about 20 years, a successive renovation of the castle and the three surrounding buildings (Forester's lodge, barn and carriage house) began.
