The castle was built on a rocky spur of the Vosges at an elevation of approximately 450 meters.
The structure was specifically designed to mirror the territorial power of the Andlau family in opposition to the nearby Hohenburg Abbey.
The 24-meter-high square keep is constructed with large-block bossage, a hallmark of mid-13th-century military architecture in the region.
The castle was abandoned as a residence in the 16th century and fell into disrepair during the following century.
The site features a rare preserved latrine oriel, a common architectural detail in medieval castles that projects from the exterior wall.
Local volunteers carry out ongoing consolidation work to prevent further collapse of the remaining stone masonry.
Château de Spesbourg is a 13th-century castle ruin located in the Vosges Mountains near Andlau, Alsace. It was constructed around 1250 by the Lords of Andlau to assert their political influence. The site is notable for its well-preserved, 24-meter-high Romanesque keep, which remains one of the most prominent features of the ruins. The castle suffered damage during the Thirty Years' War and has since transitioned into an archaeological site maintained by local heritage associations. The layout follows a classic medieval fortification design, including a residential building, a courtyard, and defensive walls. Visitors can observe distinct masonry techniques, such as the use of bossage stones on the corner towers. The site is integrated into the regional hiking network, overlooking the valley of the Andlau River. Recent stabilization efforts have focused on preserving the remaining curtain walls and the upper residential floors.

Wear sturdy hiking boots as the access path involves a steep, uneven incline through the forest.
Bring a headlamp or flashlight if you intend to examine the wall details closely, as parts of the ruins can be shadowed.
Check the local weather forecast before departing, as the mountain paths become slippery after rain.
Do not attempt the hike in standard footwear like flip-flops or smooth-soled street shoes due to the forest terrain.
The site is open year-round, though forest paths may be impassable during severe winter snowstorms.
Do not climb on the unrestored walls or remove any stones, as the site is fragile and under conservation.
