Hollow Tooth

Hollow Tooth is a stone tower ruin on the Bock Promontory distinguished by its distinctive upper section where the center has partially collapsed. The remaining walls display fortification construction techniques and sit directly adjacent to the underground casemate system.

The tower served as part of Luxembourg's defensive network and played a role in protecting the city over many centuries. Its destruction occurred in the early 19th century when the fortification was gradually dismantled following political changes in Europe.

Local residents named this structure after its distinctive shape, which resembles a damaged tooth visible from multiple viewpoints. The name reveals how people created memorable descriptions for the landmarks in their surroundings.

The site is best reached on foot by following the walking path from Place de la Constitution and passing through the casemate system. The ruin sits on an elevated plateau and is visible from above or below depending on which route you choose.

The exact cause of the damage to the upper section remains unclear, whether from siege damage, planned demolition, or natural erosion over decades. This mystery adds to the intrigue surrounding the ruin today.
