The panoramic terrace of the Vauban Dam

Just a few metres from the Covered Bridges, the Vauban Dam (or the "Great Lock", as it made it possible to flood the entire southern end of the town if needed) was built around 1690 by Tarade based on plans supplied by the military engineer Vauban. An attractive panoramic terrace, has been laid out at the top of the building, from where visitors can admire the layout of the town and its network of canals.
