 Together with the pieces of the ("Association for Nassauian Antiquity and Historical Research") founded in 1812, three originally independent museums emerged.In addition to the "Verein für Nassauische Altertumskunde und Geschichtsforschung" the ("Nassau Society of Natural Science)" and the ("Nassau Kunstverein") (art society) were responsible for these museums.Following the death of the Duke, the Hereditary Prince's Palace at Wilhelmstraße, built for his son, was now available for other purposes.
