It lies above the village of Erlenbach bei Dahn in the county of Südwestpfalz in the state of Rhineland-Palatinate.

This outwork enabled a piece of open ground known as the Leichenfeld ("Corpse Field") to be covered by a crossfire from two directions: from the north (Berwartstein) and from the south (Little France).

Its walls are 3.20 metres thick; and some of the stone ashlars show evidence of lifting marks, possibly from a three-legged lewis.

The roof platform was wide enough to deploy culverins whose longer barrels increased their accuracy.

North of the tower are the remains of an enceinte which used to surround it, and immediately to the northeast is a castle well, now filled in.
