Benningen am Neckar (Swabian: Bẽnnenge) is a municipality in the district of Ludwigsburg in Baden-Württemberg in Germany.

Along the border they built fortifications in regular distances, which included a small castrum on the south-eastern edge of today's village.

Around 150 AD the border and the fort were moved to the east towards Murrhardt, but a civilian settlement remained in place.

In the year 1351 and finally in 1497 the community passed to Württemberg and belonged to the Office of Marbach.

Systematic archaeological excavations of the Roman castrum and town were made by General Edward of Kallee in the 19th century, who had recognised its strategic importance based on military considerations.
