Did the view inspire this historic graffiti on crawiau/pileri (slate fencing) near Sling? See 2nd image for view. If investigating historic graffiti, respect it, don’t add your own. It’s part of our historic landscape. #FindsFriday #Wales #archaeology #history #heirtage #LlechiCymru #WalesSlate

A oedd yr olygfa yn ysbrydoliaeth i’r graffiti hanesyddol hwn ar crawiau/pileri ger Sling? Gweler ail lun ar gyfer yr olygfa. Ymchwilio i graffiti hanesyddol? Parchwch ef, peidiwch ag ychwanegu eich graffiti eich hun. Mae'n rhan o'n tirwedd hanesyddol. #DarganfyddiadDyddGwener #LlechiCymru #yagym
