Neuf-Brisach
Neuf-Brisach is a fortified town and commune of the department of Haut-Rhin in the French region of Alsace. The fortified town was intended to guard the border between France and the Holy Roman Empire and, subsequently the German states. It was built after the peace of Ryswick, in 1697, that resulted in the loss to France of the town of Breisach, on the opposite bank of the Rhine. The town's name means New Breisach.
Today the town is a UNESCO World Heritage Site.
