Barrage Vauban is a historic 17th-century bridge, weir, and defensive structure located in Strasbourg. Situated on the River Ill, southwest of Strasbourg's city center, it is adjacent to the Petite France quarter and offers panoramic views of the Ponts Couverts and the surrounding Petite France district. Visitors can explore the interior corridor, which houses a lapidarium displaying sculptures and replicas of statues from Strasbourg Cathedral and Palais Rohan.
Constructed between 1686 and 1690 under the direction of military engineer Sébastien Le Prestre de Vauban, the Barrage Vauban was designed to flood the southern approaches to the city in times of siege, thereby preventing enemy advances. Visitors can explore the interior corridor, which houses a lapidarium displaying sculptures and replicas of statues from Strasbourg Cathedral and Palais Rohan. The rooftop terrace provides a vantage point for capturing stunning photographs of the cityscape, especially the picturesque Petite France district. The structure's pink Vosges sandstone arches and historic significance make it a must-see landmark.
