Frankenstein Castle
In 1978, American airmen from the 435th Transportation Squadron stationed at Rhein-Main Air Base started an annual Halloween festival at the castle, which became one of the biggest Halloween festivals in Europe. In 1977, the 440th Signal Battalion organized a 13 km running competition routed along steep forest trails from Cambrai-Fritsch Army Housing Site in Darmstadt to the castle. The Frankenstein "Castle Run" was held until 2008 when all American forces left Darmstadt. The city of Darmstadt organized a final race in October 2008.
A restaurant with a sun terrace, located right below the castle towers, offers regular service as well as special events (e.g., "Horror Dinner Nights").
