The Col du Hunsrück (748 m) is a quiet and wooded pass above Willer-sur-Thur. The steady climb and beautiful nature make this a pleasant classic in the southern Vosges, with connections to both the Thur and Dollervallei valleys.

Ammertzwiller – destroyed front village and mine warfare Ammertzwiller was one of the particularly contested locations on the Sundgau front during World War I. From September 1914, the front line ran immediately west of the village. German troops held Ammertzwiller, while French positions were located near Gildwiller-le-Mont, among other places. On January 1, 1915, the entire population was evacuated. Shortly thereafter, the abandoned village itself became a combat zone. The church was destroyed on January 8, 1915. By the end of the war, Ammertzwiller was almost completely devastated. The place became particularly known for mine warfare. From May 1915, French sappers and German pioneers dug tunnels under the enemy positions and detonated them. The underground warfare lasted until early 1916 and left numerous explosion craters. A striking event was the German mine detonation on July 11, 1915. The explosion under the German outpost Sautter created a massive crater. The mine crater, now filled with water, is preserved as the "Entonnoir" and serves as a reminder of this form of warfare. German troops also built an extensive system of bunkers, shelters, and underground facilities. Today, the approximately 10.5 km long "Circuit de la mémoire d’Ammertzwiller" leads through this former front landscape. Around 15 information boards explain the local history. After the war, the residents returned to a largely destroyed village. Reconstruction left a lasting mark on Ammertzwiller. Today's Saint-Étienne church, with its depictions, preserves the memory of evacuation, war, and return. Particularly worth seeing: the water-filled mine crater and the Circuit de la mémoire d’Ammertzwiller.

Altkirch Altkirch is the historic capital of the Sundgau and lies on a striking rocky spur above the valley of the Ill. The town's origins date back to the Middle Ages. The Counts of Ferrette built Altkirch into a fortified town; from 1215 onwards, it was protected by town walls and towers. The characteristic layout, narrow streets, and remnants of the fortifications have been preserved from this medieval town plan to this day. Particularly worth seeing is the Vieille Porte, a former town gate from around 1245. For centuries, Altkirch was an important administrative and commercial center of the Sundgau. After the destructions of the Thirty Years' War, numerous buildings were newly erected. The representative town hall dates from the 18th century, built in 1778 according to plans by the Swabian architect Jean Nissler. In the 19th century, the town continued to develop: alongside its traditional importance as a market and trading place, industrial enterprises emerged, including the well-known Gilardoni brickworks. The 20th century also left its mark. After the First World War, Altkirch became part of the re-Frenchified Alsace. The memory of this period is evident, among other things, at the Vieille Porte, where a Borne Vauthier commemorates the former front line of 1918. The original Altkirch war memorial from 1927 was destroyed during the German occupation in the Second World War; preserved parts were later integrated into a new memorial. Today, Altkirch, with around 6,000 inhabitants, is an important center of the Sundgau. The historic upper town with its old houses, remnants of fortifications, the town hall, and the Sundgau Museum continues to shape the townscape. Source: Ville d’Altkirch – History of the town

This old chapel was erected after the French Revolution on the old path to Thann and fell into disrepair over time. In 1932, the community decided to rebuild it. The current small building has a simple nave, an open porch, and a small bell tower with a bell. In front of the chapel stands a statue of the Virgin Mary, which underscores the character of the place as a pilgrimage and devotional site. The chapel is dedicated to the "Mother of God of Perpetual Help" and belongs to the typical small religious monuments of southern Alsace.

It's just a gentle up and down. And all of this on a main road, but it's still somehow nice to roll along like that...
