The biggest London Plane in UK. Measured in 1965 to be 123 ft high and have a girth of 21ft at 5ft above ground. Probably over 200 years old.
Two good friends, only just over 120 years old (together)!
Your math really demonstrates how old this tree is.
I am sure if threes could talk this one could really give us some history.
Your friends gave you a great smile and expression.
