Altdischingen Castle, also called the "Old Castle", is a former (Burgstall) hilltop castle around 400 m (437.45 yd) above sea level in the Solitude state forest range of Weilimdorf, a district incorporated into Baden-Württemberg's capital Stuttgart in 1933.

[1] The castle situated 400 m (437.45 yd) south of Dischingen Castle had only been built at the end of the 11th Century and was destroyed in the mid 12th Century.

The site is bounded by a ravine on the south, by a 2.5 to 3 m (2.73 to 3.28 yd) deep trench to the north and the east side.

In front of this main ditch is an additional wall in the north and east with its own 1 m (1.09 yd) deep trench.

No visible parts of the walls and buildings have been preserved above ground.
