Louis René Édouard de Rohan-Guéméné, Prince-Bishop of Strasbourg, also lived here from 1790 and plotted a counter-revolution from the city.

The highest elevation, 543 meters (1,781 ft) NN, is found in the municipality's northeast, in the buntsandstein mountains of the Central Black Forest around Lahr.

In the foothills of those mountains that fall within Ettenheim's municipal area are the wetlands of the Seltenbach, which are protected as the Saure Matten [de] nature reserve.

[3] The coat of arms of Ettenheim displays a castle in red, with an open gate and three towers (one domed) topped with crosses, upon a field of white.

Since 1370, local town seals had depicted a Gothic structure with three towers and a crenelated wall, a reference to Ettenheim's defenses.
