The castle is categorized as a 'château de grès,' meaning it is built primarily of local pink sandstone.
It is built on a narrow, elongated rocky outcrop approximately 340 meters above sea level.
Archeological evidence suggests the castle served as a residence for the local nobility until the 16th century.
The defensive structure was partially destroyed during the Thirty Years' War.
Visible remains include the foundation of the central bergfried (keep), which showcases medieval masonry techniques.
Some chambers were hollowed out of the cliffside, providing natural insulation and structural support.
Château du Falkenstein is a 12th-century medieval rock castle perched on a sandstone promontory in the Northern Vosges Regional Nature Park. Built around 1127 by the Counts of Lutzelbourg, the fortress served as a strategic lookout over the valley. It is characterized by its troglodytic architecture, where parts of the structure were carved directly into the natural red sandstone bedrock. Much of the original keep and defensive walls remain, though the site is largely in ruins following historical conflicts. The castle was heavily fortified in the 14th century before being dismantled to prevent use by enemy forces. Access to the upper sections requires traversing narrow stone staircases and rock-cut passages. The site is maintained as a protected heritage monument rather than a fully restored museum. Visitors can explore the remnants of the cistern, residential chambers, and the elevated viewpoints that offer panoramic vistas of the surrounding dense forest. It is accessible year-round via marked hiking trails through the sandstone crags of Philippsbourg.
