The Mutzig fort is located 20 minutes from Strasbourg. Built in 1893, this fort built under the Emperor of Prussia and Germany (William 2) was never actually used despite its cost. Perfectly located on the heights with a 360° view of the Alsace plain and the Vosges mountains, the fortification could accommodate up to 7,000 men. Discover this perfectly preserved labyrinth and this city / underground life by transforming yourself into a German soldier for a few hours. Remember to cover yourself, temperature of barely 12°C but dry :)
