Although the few remaining ruins of this structure are called a castle, it appears that the site was first used as a Roman temple and then as a Christian church. Nearby are superb rock formations typical of the Northern Vosges Mountains.

The remains are not the ruins of a small castle, as the popular name might suggest, but rather the remains of a Roman or Gallo-Roman sanctuary from the 2nd century, with a second phase of use in the 4th century. It may have later been used as a Christian church. In Curt Mündel's guide to the Vosges Mountains (1911 edition), the ruins are referred to as "Meisenbacher Schlössel," and the rock below as "Ochsenstall" (Oxen Stable), probably because the rock overhang was formerly used as a shelter for cattle.
