I recently moved to live / work on The Isle of Sheppey.Have heard some local rumours / stories that there was once a Stone Circle either on the site of what is now Minster Abbey,or,the adjacent Saint Sexburgas Well.Allegedly some of the stones are in the foundations of one of the pubs below The Minster.It would theoretically be a good site,given the view over the surrounding marshes and the Medway/Thames Estuary.Have you or anyone else come across this in your investigations into The Avenue or The Medway Area?
