I just found an article, and things are getting a little weird here, because it was published in November 2022 in...
The Guildford Dragon News (!)
In 2022 the Waverley Abbey won the Woodland's Trust Tree of the Year contest. The article states "The winning yew is thought to be over 500 years old and will now go on to represent the UK in the European Tree of the Year contest."
Waverley Abbey Yew in Surrey Crowned Tree Of The Year 2022 from The Guildford Dragon News website.
From the results of the 2023 European Tree of the Year contest:
The winner of UK Tree of the Year 2022 is a yew perching on the ruins of Waverley Abbey, in Surrey, founded 900 years ago by the reforming Cistercian religious order.
After the abbey was dismantled in 1536 following the Dissolution of the Monasteries, the yew tree sprung up and has been a faithful guardian of the ruins for nearly 500 years. It is a spectacular tree with roots that sprawl out above ground before plunging into the earth. Its multi-stemmed form is dotted with holes, crevices and areas of decay that provide valuable habitat for wildlife.
