In 1967,
GCHQ set up an "experimental radio station", a secret research facility, on the site. The site was still active in some capacity until the mid-1990s, and traces of the former communications mast bases can still be seen on aerial photographs. The most remarkable object of the facility was a tall wooden lattice tower, which was one of the tallest objects in the United Kingdom built of wood. It is possible that this tower was a relic of the wartime
Chain Home network, although its lattice pattern is of another type. ==See also==
