Capenhurst Tower
In 1999 the journalist Duncan Campbell published claims that a fifty metre high tower on the premises of the uranium enrichment plant had been used to intercept telephone calls transmitted by microwave between the British Telecom towers at Gwaenysgor, Clwyd, and Pale Heights, near Chester. Campbell claimed that the interception was conducted by the Government Communications Headquarters, GCHQ, initially from a temporary installation on the roof of the plant until commissioning of the tower in 1990.
The main route for phone calls between the Republic of Ireland and the United Kingdom was via the submarine fibre optic cable UK-Ireland 1, landed at Holyhead, Anglesey, then transmitted by a microwave link. Campbell claimed that calls were monitored by GCHQ until 1998 when the Irish telecommunication system was changed.
The tower was demolished in 2004.

Famous quotes containing the word tower:
“What did it matter where you lay once you were dead? In a dirty sump or in a marble tower on top of a high hill? You were dead, you were sleeping the big sleep, you were not bothered by things like that. Oil and water were the same as wind and air to you.”
—Raymond Chandler (1888–1959)
