A striking medieval castle, high on a ridge above the Selke Valley, was built between 1120 and 1180 and since then has been used in a number of different ways. Because of its position it was never captured. Today the castle is a museum and one of the most popular places to visit in the Harz Mountains. The museum is on the so called "Romantic Road" and contains amongst other things a falconry, and a restaurant that offers a special 'Knights' Menu'. Since 2006 a European-wide singing competition has been held in the castle known as the 'Minneturnier', which refers to a singing contest in the Middle Ages, and today famous singers from Austria, Italy, France, Switzerland and Germany take part. The castle is number 200 on the Harzer Wandernadel hiking network.
