The Grey Stone is a dolmen located on the heights of Montivilliers that inspired legends and beliefs. A 15th century version of the legend of the Grey Stone will be told at the crossroads, in front of the megalith. Other stories, drolatic or terrifying, will punctuate this walk, which will take you over the water and then into the forest through the gardens of Colmoulins. Proposed by the Maison du patrimoine et des cités provisoires de Gonfreville-l'Orcher
