Walpurgisnacht is celebrated on April 30-May 1 at the Hexentanzplatz ('witches dancefloor'), a high peak above the Harz Mountain town of Thale in Germany. From here witches on broomsticks and he-goats are believed to fly at midnight to places of old pagan sacrifices in the Harz Mountains, especially to Brocken, the highest point in the mountains, which is often claimed to be Mussorgsky's 'Bald Mountain'.
