Ill river

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