Culture and History
The parish church of Saint Gregory in Ohnenheim has been documented since 1371. In the late 18th century, the church was extensively remodeled: the nave was demolished and rebuilt; the work is dated to 1777–1778? The medieval choir tower was preserved.
In 1660, the Amish signed the Convention de foi commune at a remote farm in Ohnenheim that is now a mill. The tumulus graves of Ohnenheim include a Hallstatt-period wagon burial discovered in 1917.
The de la Romance park and garden is home to centuries-old willows. It is located in front of a former farmhouse in Ohnenheim dating from the 17th century.
Renting a holiday apartment in Ohnenheim can be part of an individual travel plan.
