 Since 1994, Dornhan has maintained partnership relations with the French community Pont-de-Vaux in the Auvergne-Rhône-Alpes region.In the Zitzmannsbrunnenbach Valley (also known as Bettenhauser Valley) between Dornhan and Bettenhausen is the so-called Wasserhäusle, a fully preserved pumping station dating from 1889, which was the origin and part of Dornhan's water supply.In Bettenhausen there is also a portrait of the risen Christ in the church of St. Konrad, which Hans Marx von Bubenhofen donated in 1596.
