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

The French and European National Cycleway is a great cycleway winding along side of the Rhine Rhone Canal with very little climbing, for those who do not like to climb. However those who are climbing shy, must be aware of the wind in this area. A lot of the locks still have the former lock man’s house which adds a bit of charm to every lock. One is never alone on this route as there is a constant passing of bicycles, both leisure and racing bikes.

Very grateful for this highlight. Perfect stop. But beware, don't think you can also take advantage of the restaurant, you have to make a reservation for that. You can get an ice cream sundae and drinks here.

Ammertzwiller is a quiet Alsatian village that is surprisingly convenient for cyclists on the road. There are a few mini markets, restaurants and even a chemist – ideal for stocking up on provisions or taking a break. The village is set in rolling countryside and offers lovely picnic spots overlooking the fields. Information boards in the village tell the story of the local history during the First World War, making this stop not only practical but also meaningful."
