Fort de Mutzig, also known as 'Fort Kaiser Wilhelm II', is located near the town of Mutzig in the Bas-Rhin region of France. The fortress was built by the Germans towards the end of the 19th century and the purpose of Fort de Mutzig was to defend Strasbourg. Interestingly, it was the first new fortification to be built in German territory, following the invention of high explosives, which rendered many types of masonry fortifications obsolete at the stroke of a pen.
The beautiful scenery is also an experience in itself, so make sure you bring your camera along for the ride.
