Vauban Dam

The Vauban Dam is a water control structure in Petite France that crosses the Ill River with sturdy stone arches and retaining walls. The construction combines multiple levels: a pedestrian walkway sits on top, stairs lead down to a viewing platform, and beneath lie sluice mechanisms for controlling water flow.

Built in 1690 under Louis XIV, the dam regulated water levels and defended the city from military threats. Over time it lost its strategic military role but remained as a testament to engineering innovation and urban planning.

The structure shows how medieval and early modern cities managed their waterways, blending practical engineering with defensive purposes. Locals and visitors walk here to understand how communities adapted to floods and security threats through architecture.

The structure is freely accessible during daylight hours, with stairs or an elevator leading to the viewing platform. Wear sturdy shoes, as the stone surfaces can become slippery when wet.

A striking feature: the dam contained mechanisms that could deliberately flood entire neighborhoods to stop enemy armies from advancing. This flooding defense system was an unusual but effective concept in early fortress design that few visitors realize while walking above it.
