Ill river

The 223 km long river has its source on the Glaserberg in Winkel with a resurgence in Ligsdorf. Its source is located to the east of the village, at a place which in 1591 was called the Illentsprung, i.e. the origin of the Ill. The latter flows into the Rhine at Offendorf downstream from Strasbourg towards Gambsheim. Before the Rhine was rectified, the Ill flowed into the Rhine at La Wantzenau. The commune of Illzach takes its name from this river.
