Wacken is a municipality near the town of Itzehoe in Schleswig-Holstein, Germany. Wacken was first mentioned in 1148, but there were probably some settlements before, which is proven by the trove of Germanic artefacts. Today, Wacken is famous for annually staging the world's biggest open air metal festival, "Wacken Open Air", which has hosted popular metal acts such as Iron Maiden, Saxon, Alice Cooper, Deep Purple, Motley Crue, Slayer, Rammstein, Motorhead and Judas Priest. Due to the festival the entry sign to the village is frequently a victim of road sign theft. Also the festival occurs every year once in the month if July and usually it has stormy weather at the time.
