Centre of the Island Stone,
This ancient Centre of the Island Stone, located in the roadway of Route de Saint-André (approx Perry’s 22D9.0 4.8), was the marker for the centre of the mainland of Guernsey prior to the reclamation of the Braye du Valle in Napoleonic times. Consequently this joined the former small island of Clos du Valle to Guernsey and effectively moved the centre of the Island.
