Hadrian's Wall, a UNESCO World Heritage Site and a famous landmark of Roman Britain, has suffered irreparable damage due to an act of vandalism.
The damage occurred when a beloved sycamore tree, known as the Sycamore Gap tree, was felled at the end of September.
The tree's main trunk collapsed over a section of the wall after it was chainsawed down by an unknown vandal.
Archaeological assessment has revealed that fragments were chipped off the wall's facing stones, and cracks were left in the stones due to the tree's fall.
The investigation into the chainsawing incident continues, and four people have been arrested in connection with it. The Sycamore Gap tree was regarded as an icon of north-east England, and its loss has saddened many.
