History+
The exact construction period of the Greiffenclau Manor House, also known as Rüffer's House, is presumed to be between 1590 and 1600, with the Stupanus brothers considered as possible builders. A coat of arms of the von Heusenstamm family above the cellar entrance suggests that Martin von Heusenstamm, who was bailiff in Höchst around 1540, might have been the patron. There are no detailed records regarding the exact time of its transfer into the possession of the Greiffenclau family or the subsequent ownership.
