Tips from the Community

July 17, 2025, Église Saint-Géréon

The original church of the lower village parish was dedicated to the Virgin Mary and then to Saint Anthony the Hermit, but in 1842, Father Acker established Saint Geron as the main patron saint. In 1802, the two parishes of Pfetterhouse were united, and there was only one church. The current bell tower was built in 1900 by the architect Alexandre Louvat from Mulhouse. The old furnishings were gradually replaced. This church is the only one in Alsace to have Saint Geron as its patron saint.

This is an intersection in the village Winkel with some well-maintained traditional half-timbered houses. The source of the river Ill is located 400 meters further south on the Rue Principale / Rue de la Charrière at another highlight: https://www.komoot.com/highlight/4448431 If you follow a trail off the parking area there's a wooden sculpture and a modest spring in the meadow, though the source is often not producing much visible water.

This is a (often dry) fountain at a highway intersection in the village called Winkel, not the location of the source of the river Ill; that's 850 meters to the south at another highlight: https://www.komoot.com/highlight/4448431 But the source is often not producing much visible water. So it's perhaps fitting that Komoot's automatic translation doesn't reliably avoid messing up place names. While that's confusing for users, we can try to focus on the humor: Unless the highlight author puts the title "Illentsprung" (German for "Source of the Ill river") in quotation marks, it is displayed to me in English as "Source of pain" ... 🤣 ;-)

First mentioned in 1144 and rebuilt in 1781, this remote chapel is tucked away in a valley near Sondersdorf. It was once a parish church and later a place of pilgrimage, with an unusual painted coffered ceiling and Gothic tabernacle.

At Rue Principale 41 in Ligsdorf is this striking half-timbered house from the 18th century, recognizable by its carefully balanced symmetry and the decorative diamond pattern in the timber frame. The house is a beautiful example of the traditional building style in the Sundgau. Also nice is that the mailbox is a replica.

The village is known in Alsace because the Ill River, which joins the Rhine a few kilometers north of Strasbourg, has its source here. The source of the Ill, located east of Winkel at a place designated in 1591 as Illentsprung, meaning origin of the Ill, in an orchard on the slopes of the Glaserberg. Its current powered the waterwheels of sawmills and mills.

The spot is marked by striking trees around a small chapel. For a stop, you have a large picnic area 100 m lower.
