A TREE that Scots freedom fighter William Wallace was famously chained to by the English is being preserved after it was discovered behind a supermarket.

For nearly a year, experts have been examining two chunks of oak in order to find out if they really came from the same tree named in a local legend.

The chunks were found at the site of the former Gourock Ropeworks, Inverclyde, and from a tree thought to have stood in the grounds of the Holy Family Church. According to local legend, Wallace was chained to the tree in 1305 after his capture by the English before being transferred to London.

The segments of tree were examined by tree specialist Dr Coralie Mills – one of just three dendrochronologists in Scotland and only a dozen in Britain – in March last year to try and identify how old they are.

Both pieces will now be preserved to let them dry out amid plans to put them on public display after being moved from their spot near Lidl in Port Glasgow.

They can now be dated back to the 1700s but further evidence, including pictures of the original tree, suggests the oak is almost certainly from the days of Wallace.

In her report, Dr Mills said: “If we go back 500 years from 1768, when the tree was said to have been bored and pitch poured in, then we get to the mid 13th century, and the tree could have been a decent size at the time of William Wallace’s capture in 1305.

“In other words, despite the dendrochronological age of the sampled part of the tree being late 18th century, the organism as a whole could have been much older.

“We cannot refute the Wallace tradition on the basis of the dendro results.”

History buffs Cha Halliday, 53, from Greenock, along with friend Sean Donnelly, 48, from Inverkip, tracked down the last remnants of the tree three years ago after stumbling on a local link to Wallace and conducting their own research.

Cha said the new findings are a breakthrough He said: “The legend of the Wallace Tree lives on.

“The sections are dated to the 1700s but those are off-shoots from the original tree and who’s to say that wasn’t four or five hundred years old as well?”

The tree was carefully removed on Sunday by Wallace Civil Engineering to a safe storage site in Gourock.
