Set on a clifftop overlooking Corbière lighthouse on Jersey’s south-west tip, the Radio Tower is a striking observation tower built during the Second World War. In 1941, the German High Command was ordered to convert the Channel Islands into unassailable fortresses. The numerous artillery batteries that were set up needed an effective system of fire control, and so a comprehensive system of naval direction-finding and range-finding towers known as Marinepeilstäden unde Maßstellen (abbreviated to MP) were planned. Only three towers were completed in Jersey, with the Radio Tower known as MP2.
MP towers are unique to the Channel Islands, not being found anywhere else on the Atlantic Wall. Constructed of reinforced concrete, MP2 is 17.8 metres high with walls no less than 2 metres thick.
MP2 was originally camouflaged to resemble an 18th-century Jersey granite round tower. At the top of the Tower was a small cabin housing radio direction-finding equipment that enabled German vessels to obtain their bearings. Surviving features from the 1940s include the concrete staircase and a steel door to the ground floor.
MP2 was adapted for use by the States of Jersey Harbours and Airport Committee in 1976. A glass-panelled control room was added to the top of the Tower from which a duty officer could monitor the radio traffic of all shipping passing through the entrance to the English Channel.
In January 2006, the MP2 Tower transferred ownership to the Public of the Island of Jersey, under the management of Jersey Heritage.
