PROTESTERS against a proposed eight-turbine wind farm near Graveley claim it would tower above surrounding villages and be visible from 30km distance. The 127-metre (417 feet) turbines would be twice the height of Ely's 66-metre cathedral tower and taller than the dome of St Paul's Cathedral, in London, they claim. (England's tallest cathedral is in Salisbury, where the spire reaches 404 feet.) The Cotton Farm Action Group claims 97 per cent support in Toseland for its opposition and 88 per cent in Graveley. The group is urging people from surrounding villages to attend an exhibition this weekend mounted by npower renewables, the scheme's promoters, in the Offords Village Hall.
