The town of Winkel welcomes you on this tourist trail called "Moroccan Trail" for a meeting with its history and heritage.

Between 1929 and 1940, to guard against any enemy invasion, France built along its borders to the North East a veritable wall of fortified works: the Maginot Line.

In Winkel, in its southernmost part, its unfinished construction between 1939 and 1940 was closely linked to the life of a Moroccan infantry regiment. In their memory, a path already bore their name. It is now quite a journey.

Three circuits are offered: 2,6 km - 3,6 km, 5,6 km.

You will also discover rich, varied environments, typical of the Alsatian Jura, made up of forests, pastures and remarkable landscapes, as well as a set of remains of the Maginot line (casemates, anti-tank defenses, shelters, etc.) today witnesses of history and an authentic element of local identity.

Take advantage of your visit to Winkel to discover the source of the Ill, the main waterway in Alsace, located a few steps from the Sentier des Marocains.

The Km 0 trail allows you to discover on a 7,5 km course, in flat and wooded terrain, the various vestiges of the three fronts: French, Swiss and German. The route can be done in both directions.

From 1871 to 1914, Pfetterhouse was the village of the three borders. The terminal of the three powers, where the borders of France, Switzerland and Germany met, had become a tourist attraction and a place of international conviviality.

In the fall of 1914, the French fixed the start of the Front at the Swiss border of Largin. The boundary marker n ° 111 then became the Zero Kilometer of the Western Front.

The Friends of the Zero Kilometer association works, through this discovery trail, to promote and promote this place steeped in history and symbols.

The work it has undertaken has made it possible to restore several concrete structures on the front line, freely accessible and secure. Topoguide downloadable from the website of our partner Visorando.

Porte du Sundgau, Illfurth is also a high place of history. The fighting of the 1st World War fell in the Sundgau from August 1914. Indeed the French blew up the viaduct of Dannemarie and the front stabilized and extended from the Vosges to the Swiss border.

The front line passed a few kilometers from Illfurth on the Heidwiller side. During this visit, you will discover several bunkers with multiple uses, both ammunition depot, observation post or location of artillery pieces, also the location of a second large cannon located near the Church de la Burnkirch and several casemates.

The Aschenbach casemate is one of 32 works of this type built in the Sundgau between 1936 and 1940 in order to reinforce the Maginot line. The Altkirch sector also had 7 artillery casemates with 2 pieces of 75 mm each (range 11 km). Their main mission was to prevent a possible enemy overflow by the Basel region and Swiss territory.

This reinforced concrete casemate has an armored observation bell, 2 47 mm anti-tank guns, 2 8 mm machine guns, 3 machine guns and 3 grenade launchers.
About 15 men occupied the structure, commanded by a lieutenant and 3 non-commissioned officers.

This former military structure, decommissioned in 1970, was taken over in 1991 and, as local historical heritage, has been completely restored by the members of the Maginot Memorial Association of Haute-Alsace. Today it is the only witness of this type that can be visited on the Maginot line.

It was here that on April 26, 1942, General Giraud's famous escape to Switzerland took place. While the owner of the premises was talking with the soldier in charge of monitoring the border, promising him eggs and cheese to improve his everyday life, the future head of the French National Liberation Committee, accompanied by smugglers, slipped into the deep Swiss beech groves to reach Algiers some time later.
