Much debate surrounds the exact position of the centre of Great Britain. Dunsop Bridge was officially recognised by the Ordnance Survey in 1992 as the neareset village to the centre of the British Isles and BT marked this by placing its 100,000th telephone box on the village green. However, the actual centre of the British Isles is in fact at SD 64188.3 56541.43, at Whitendale Hanging Stones on the hills seven kilometres north of Dunsop Bridge. Others would argue that the centre is much further north in Haltwhistle. It all depends on how you calculate it.
