The Rudston Monolith is an impressive menhir-type megalith or standing stone, located in the churchyard of All Saints Church, Rudston. It is well worth a detour if you're touring the East Yorkshire coast or the Wolds (5 miles W of Bridlington on the B1253 Sledmere road). The stone, which is estimated to weigh about 40 tonnes and stand 8 metres high (with a further several metres buried in the earth) was dragged to this hilltop site from Cayton, near Scarborough, and erected in around 1600 BC. There are a number of nearby prehistoric stones that suggest it was the centrepiece of a curses group, possibly with calendar significance as well as being a site of congregation.
