歴史的な
The Château du Grand Ringelstein (or Château Ringelsbourg) is a ruined castle in the commune of Oberhaslach in the Bas-Rhin département of France.Dating from the beginning of the 13th century, it is built around several sandstone rocks at an altitude of 644 m. At the summit of the rocks there are only meagre remains of buildings, including the remnants of a pentagonal keep in the north, the most accessible part of the site.
