The Preston Twin is one of 70 ancient trees set to be dedicated to Queen Elizabeth II to mark the Platinum Jubilee.
The elm is thought to be about 400 years old, and until 2019 was one of a pair standing in Preston Park.
Sadly, when Dutch Elm Disease struck one had to be felled, but the other one has so far survived.
The Prince of Wales announced the dedication yesterday as patron of The Queen’s Green Canopy (QGC).
