The rock castle of Neudahn, in the southwestern Palatine Forest in the German state of Rhineland-Palatinate, is located at the northern end of an elongated ridge near the town of Dahn.

Immediately below the castle the Moosbach stream, which is impounded in a small woog used to feed an old mill, empties into the Wieslauter.

[1] p Within a hundred years of the castle being built, the Mursel family died out, and its possession passed to the related Altdahn line.

After the last lord of Dahn, Ludwig II died in 1603 in his castle at Burrweiler, Neudahn was returned to the Prince-Bishopric of Speyer.

From then on the castle was used by the episcopal Amtmann as his headquarters until French troops finally destroyed it in 1689 at the start of the War of the Palatine Succession.

Of the oldest – late Hohenstaufen – castle on the vertically hewn, central rock outcrop, which is just under 20 metres high, the only surviving features are a cistern at the western end and the southern wall of the small palas with its window and door openings.

At the northwestern end of the main rock outcrop in the south was a late medieval domestic building and, west of that, a well.

A formerly plastered newel tower from the same period on the northwestern edge of the rock outcrop leads up to the upper ward.
