We find this rock arch near the village of Hauenstein in Rhineland-Palatinate.
Park at the Netto supermarket on Pirmasenser Straße. On the south-eastern edge of the car park, a path leads to the rock gate, which is reached after about 120 m. The larger opening is not an arch because it is not a through opening.
It's dimensions: Span: 0,5 m; Height: 1,0 m.
