The castle ruins are situated at an elevation of approximately 530 meters above sea level.
The defensive walls utilize the natural volcanic rock formations as part of their foundation.
The site was partially abandoned and fell into disrepair by the mid-16th century.
The Brothers Grimm identified the Nideck ruins as the setting for their folktale regarding a giant girl who finds a peasant plowing in a field.
Château du Nideck consists of the ruins of two separate medieval castles built on a volcanic rock spur in the Vosges Mountains of Alsace. The twin structures, known as the upper and lower castles, were constructed in the 13th century by the Lords of Geroldseck. They served as a strategic fortification overlooking the Hasel valley. The site is accessible only via a hiking trail leading from the Nideck waterfall area. The remaining architecture includes parts of the residential buildings and curtain walls built from local red sandstone. The site has been listed as a Monument Historique since 1898. Local folklore inspired the Brothers Grimm, who wrote 'The Giant's Daughter' based on legends surrounding these ruins.
