Wunderland Kalkar
Kalkar, Germany
Wunderland Kalkar is the 1985 completed but never activated nuclear power plant ‘Kernkraftwerk Kalkar’, now being used as an amusement park. Due to its fast breeder reactor, at the time it was also known as 'Schneller Brüter Kalkar’. The cooling tower now has a climbing wall on the outside and a swing ride on the inside. Wikipedia
