Barrage Vauban

[1][2][3] The barrage was constructed from 1686 to 1690 in pink Vosges sandstone by the French Engineer Jacques Tarade according to plans by Vauban.

The principal defensive function of the barrage was to enable, in the event of an attack, the raising the level of the River Ill and thus the flooding of all the lands south of the city, making them impassable to the enemy.

This defensive measure was deployed in 1870, when Strasbourg was besieged by Prussian forces during the Franco-Prussian War, and resulted in the complete flooding of the northern part of the suburb of Neudorf.

Within the structure an enclosed corridor links the two banks and a lapidarium serves to display ancient plaster casts and copies of statues and gargoyles from Strasbourg Cathedral and Palais Rohan.

[3][4][6] The Strasbourg Museum of Modern and Contemporary Art and the Commanderie Saint-Jean, now home to the prestigious École Nationale d'Administration, are both adjacent to the northern end of the barrage.
