Ramstein Castle lies west of the village of Scherwiller in the Bas-Rhin province in France. This area is also known as the Northern Alsace or the Middle Vosges.
Ramstein Castle is built on an rocky outcrop on the same mountain slope as Ortenbourg Castle, which is situated a couple of hundred meters further up. It was primarily built as a siege castle to Ortenbourg Castle, in 1293. It was the subject of several construction campaigns in the 14th and 15th centuries. It was apparently inhabited at the beginning of the 16th century. And, like Ortenbourg Castle, it was set on fire the Swedes in 1633.
The remains of this small castle are a large part of the keep and vestiges of walls of the bailey flanked by 2 semicircular turrets. It's very much overgrown and access is prohibited due to the danger of falling stones.
This castle is not worth a visit on itself but if you're walking towards Ortenbourg Castle, it's on your way.
