Aldingen lies on the eastern edge of the Baar region at the foot of the Swabian Jura, and within sight of the Dreifaltigkeitsberg (Holy Trinity Mountain).

During the restoration of the Protestant Mauritius church, archaeological research resulted in the discovery of evidence that allows the origins of the town to be traced back to the 4th century AD.

[3] The town was first mentioned in official documents in 802 in a deed of gift of the Abbey of Saint Gall.

Aldingen is located on the Plochingen–Immendingen railway, and, after having been discontinued as a stop in 1977, again became a train station in 2003 with the establishment of the Ringzug.

The Bundesstraße 14 (federal highway) between Rottweil and Tuttlingen passes through the eastern portion of Aldingen.
