Pydna is a former American missile base in Kastellaun, Germany named Wueschheim Air Station.

Nuclear-equipped MGM-1 Matador, MGM-13 Mace, MIM-14 Nike Hercules and BGM-109G Ground Launched Cruise Missiles were stationed here.

It now hosts Nature One, a famous open-air electronic music festival.

Festival facilities now use the same bunkers that were once home to 64 Ground-Launch Cruise Missiles (GLCM) (BGM-109), Tactical Nuclear Missiles, under the operational control of the 38th Tactical Missile Wing of the United States Air Force.
