Schloss Freudenberg was built in 1904/05 on designs by architect Paul Schultze-Naumburg in a park, on a commission by the painter James Pitcairn-Knowles and Marie Eugénie Victoire Guérinet (1870–1959).

After World War I, the residence was made a casino of the French army, and then a summer location of the Palast Hotel in Wiesbaden.

After World War II, the U.S. army ran an officers' mess there for the Camp Pieri barracks nearby.

The exhibition is devoted to sensory experiences, such as a Botanical Theatre based on the painting of that name by Paul Klee, a Windharfe, Goethe's Theory of Colours (Farbenlehre), and a Tastgalerie with objects to touch without seeing them.

[3] The project is run by around 80 women and men of 15 nationalities who take care of the building and the park, organise a shop, seminars, vacation programs, a cafe and a Dunkelbar, an unlit bar in which visitors experience what it feels like to be blind.
