Britain’s tallest, prehistoric standing stone is in the All Saints churchyard in Rudston, East Yorkshire. Standing about 8 metres high, it is nearly 2 metres wide and estimated to weigh about 40 tonnes. This giant block of grey sandstone or gritstone was thought to have been quarried at Cayton Bay (the nearest source of this type of stone) and then brought the 10 Miles to Rudston in either the late Neolithic or early Bronze Age. However, this is not proved and is just conjecture. It may just have been brought naturally to the site as a glacial erratic. The Norman churchyard of All Saints that it stands in, is of course some 3000 years younger.
The site of this massive stone, sat amongst the gravestones, is definitely worth a visit if you are nearby.
