Jurors began deliberating Thursday in the case of two men charged with cutting down the Sycamore Gap tree that once stood along the ancient Hadrian’s Wall in northern England.

Daniel Graham, 39, and Adam Carruthers, 32, have pleaded not guilty to two counts each of criminal damage. The former friends each testified that they were at their separate homes that night and not involved.

Justice Christina Lambert told jurors in Newcastle Crown Court to take as long as they need to reach unanimous verdicts in the trial that began April 28.

The tree was not Britain’s biggest or oldest, but it was prized for its picturesque setting along the ancient wall built by Emperor Hadrian in A.D. 122 to protect the northwest frontier of the Roman Empire.

The tree was long known to locals but achieved international fame in Kevin Costner’s 1991 film “Robin Hood: Prince Of Thieves.” It sat symmetrically between two hills along the historic wall and was a draw for tourists, landscape photographers and those taking selfies for social media.

Prosecutors said the tree’s value exceeded 620,000 pounds ($830,000) and damage to the wall, which is a UNESCO World Heritage Site, was assessed at 1,100 pounds. Andrew Gurney, a lawyer for Carruthers, said Graham’s story didn’t add up and he was projecting his guilt on his former friend.

“Is that a plausible chain of events or is that the desperate story of a man caught out?” Gurney said.

Wright mocked the duo’s defense, saying common sense and a trail of evidence should lead jurors to convict them for their “moronic mission.”

Prosecutors showed grainy video from Graham’s phone of the tree being cut down — a video sent shortly afterward to Carruthers’ phone. Metadata showed it was taken at the tree’s location in Northumberland National Park. Data showed Graham’s Range Rover had traveled there.

Wright said he couldn’t say who cut the tree and who held the phone, but the two were the only people in the world who had the video on their devices.

Text and voice messages exchanged the following day between Carruthers and Graham captured their excitement as the story went viral.
