Two men have been found guilty of criminal damage for felling a landmark sycamore tree in northern England.

Daniel Graham, 39, and Adam Carruthers, 32, were each found guilty of two counts of criminal damage, one relating to the tree and the other to Hadrian’s Wall that the tree fell on, according to the UK’s PA Media news agency on Friday.

The verdict was handed down following a trial at Newcastle Crown Court in northeast England. Both men will be sentenced on July 15.

The tree had stood sentinel on Britain’s Roman-built Hadrian’s Wall for more than 200 years before being “deliberately felled” in September 2023 in what authorities at the time called an “act of vandalism.”

The sycamore tree, located in the Northumberland National Park in northern England, was made famous to millions around the world when it appeared in Kevin Costner’s 1991 blockbuster movie “Robin Hood: Prince Of Thieves.”

The tree – at a spot known as “Sycamore Gap” – was located on the historic UNESCO World Heritage listed Hadrian’s Wall, which was constructed around 1,900 years ago to guard the furthest northwestern frontier of the Roman Empire.

During the trial, prosecutor Richard Wright KC said the felling was an act of “mindless vandalism.” He detailed how the two men drove 30 miles (48 kilometers) at night to reach the tree before one cut it down while the other filmed it.

The jury determined Graham and Carruthers caused £622,191 (about $826,000) of criminal damage to the tree and £1,144 ($1,500) of damage to Hadrian’s Wall, according to PA Media.

Jurors heard how the two men sometimes worked together and had experience of cutting down large trees. Although originally the “best of pals,” the two defendants now appear to have fallen out and their friendship has “unravelled,” the court was told.

During testimony, Graham told the court that Carruthers had told him that the tree “was the most famous tree in the world” and had spoken about cutting it down, reports PA Media.
