The German soldiers who died in the Battle of Mühlhausen in August 1914 are buried there, including the first casualty of World War I. It's a bit off the beaten track and very well maintained.

Beneath the forest canopy, you can discover numerous traces of bygone times, still visible or legible; only the "barracks" have disappeared. During a guided tour with one of the site's enthusiastic volunteers, you can explore the underground tunnels and discover the organization of this impressive military infrastructure. Of course, you can also visit the surface infrastructure yourself, following the marked route, where the panels provide detailed explanations. An application, "Site du Grand Canon de Zillisheim," is also available for download.

The Illfurth German War Cemetery was established by the French military authorities in April 1920. As a collective cemetery, it housed some of the fallen soldiers from the battles of August 7 and 17, 1914. The transfer of war dead to Illfurth, who had been provisionally buried in 64 municipalities and districts during the war or who had died in French captivity, ended in 1924. Among those reburied was the first German casualty of the 1914-1918 War on the Western Front, Lieutenant Albert Mayer, who fell on August 2, 1914, while on patrol. The first French soldier also lost his life in this battle. Several memorials erected in field cemeteries during the war were also relocated to Illfurth.

The Mathieu Ritter Observatory offers a beautiful view of Rhine Island, but it is too far away for photographers wishing to capture wildlife up close.

The site is in the middle of the forest, but a good path makes access easy.
