User:Nigelstrange!!/Black Ditch Chertsey

Chertsey was founded in the year 666 around the abbey.In medieval times a course of ditches were built to irrigate the local farms and supply water to the moat around the Abbey.The source was taken from the River Bourne ,flowed under London Street and into the Black Ditch.This fed various irrigation ditches,but most importantly fed the moat.This was fed via an underground tunnel beneath the Abbey to reappear on Abbey Green and on to the fish ponds.In the underground tunnel is a room approx under the old Abbey,this was always known as the Monks Tunnel,but in fact was a waterway.The supposedly real Monks Tunnel went from the Abbey to St Annes Hill verified by people of last generation.The Black Ditch then fed into the Abbey River and then very shortley into the Thames.
