This is just a small selection from approximately 150 images of the arborglyphs (arboreal graffiti) on the famous Meilkleour beech hedge in Perthshire. All images from the roadside.
The beech hedge was planted in the autumn of 1745 by Jean Mercer and her husband Robert Murray Nairne on the Marquess of Lansdowne's Meikleour estate. It is the tallest and longest hedge in the world, reaching 30 metres (98 feet) plus in height and 530 metres (1,740 feet) in length.
The hedge has been a popular visitor attraction since the early 20th century, if not earlier. Some of the earlier dates are not always clear, certainly several from 1910 to 1930's. Declarations of existence before and perhaps the latter to of have survived the first world war.
Virtually every tree has some graffiti on it, though there is just one that seems to have evaded the knife, having perhaps become sacrosanct.
