CAT was founded in 1973 by an eclectic, experimental community of architects, engineers, builders and organic growers, led by businessman and environmentalist Gerard Morgan-Grenville. They felt compelled to seek alternative ways of living in response to an international oil crisis, ignited by the Yom Kippur War in Israel, that saw governments across Europe ban driving on Sundays and impose rations on heating. In 1975, a visitor centre was opened to increase public awareness and engagement, setting the tone for CAT"s unique identity: part research centre, part tourist attraction and part educational hub.
