The second major watercourse is the Ehningen Krebsbach, which flows south-west of the old village before merging into the Würm.

Mauren's Schlossgut, or estate, is located on the border between the Upper Gäu and the Schönbuch in the Würm river valley.

In 1943 it was bombed by a British air raid, when due to fog, it was confused with nearby Boeblingen.

The first documented mention of Ehningen can be dated to 1185, when the knight Albertus de Ondingin purchased a manor in Herrenberg.

Albertus de Ondingin was a member of the local nobility, and in all likelihood was a vassal of the Count Calw.

In medieval times the size of Ehningen remained relatively constant, and the settlement was limited by the so-called "Etters".

In 1850 Ehningen had three Catholic and 1634 Protestant inhabitants, who lived and worked in 308 primary and 88 outbuildings.

It was only after the end of World War II when a Catholic parish was established in the wake of the resettlement of displaced persons.

The Protestant Marienkirche (St. Mary's Church) dates from the 15th and 16th centuries and is built in the Gothic style.

The town's crest is a golden duck's foot clutching a red apple on a field of blue.

Ehningen is a typical village in the catchment area of Boeblingen, Sindelfingen and Stuttgart, with a very high percentage of commuters.

Rail line S1 (Plochingen-Stuttgart-Herrenberg) on the Stuttgart S-Bahn commuter trains have run on this route since 1991.

It lends its name from the inventor of the first friction match, Jacob Frederick Kammerer, who was a native to the town.

The school social worker at the Friedrich Kammerer school provides individual assistance and counseling, social education group work and projects, community work and networking as well as open leisure facilities.
