A wonderful museum that contains a huge work done by Edouard Castres in 1881, which is one of the works that you will not see in the whole world, as this work, which is 112 meters long and surrounds the place, depicts the eastern French army under the command of General Bourbaki while fleeing to Switzerland during the Franco-Prussian War in the harsh winter of 1871. Pictures, drawings, and statues of this incident are all around the museum. This museum is visited by visitors from all over the world.
