Mengham is the largest settlement on Hayling Island in Hampshire, England. It is the largest shopping area on the Island, and has three schools and a Library. There is an old Church, St. Mary's toward the northern edge of the settlement.
There is said to be a 'grave' in St Mary's churchyard which is in fact an entrance to a tunnel. This tunnel allegedly goes down to the shore and in past times smugglers used it to bring contraband items into the mainland. The tunnel, found under the name "Mary Gritt's" leads around 1/2 a mile underground. Where there has been a cave-in, a lot of wildlife is seen emerging from the grave.
