In 790, Gau-Heppenheim had its first documentary mention as Hepfanheim when several holdings were granted to Lorsch Abbey.
The former castle complex, mentioned about 1500, was utterly destroyed in 1766 by a lightning strike and the ensuing fire.
Until the late 18th century, the place belonged to the Elector of the Palatinate.
