RAF Menwith Hill
This British military base located near Harrogate, North Yorkshire, is the largest electronic monitoring station in the world. It was originally intended to monitor communications going in or coming out of the now defunct Soviet Union and the Eastern Bloc countries. Today, with the Cold War over, its facilities are being put to other uses. Although its mission is to provide intelligence support for the U.S., the U.K. and “allied interests,” a very broad mandate, and as such is super secret, there is evidence that it has been involved in drone attacks, industrial espionage, wide-scale espionage on the general worldwide population through ECHELON, and, most recently, intercepting the then Russian President Dmitry Medvedev’s encrypted telephone calls during the 2009 G-20 London Summit. A real doozy you’ll never visit.
