This reminds me of "The Street" by H.P. Lovecraft. He describes what the street has witnessed, though did not understand, from the time it was a dirt road, through the industrial age, through the world war.

I thoroughly enjoyed this. I would check the last line, is "they" a typo?

interesting concept for a poem. If the tree was left alone long enough it would be great to talk and listen to what it had witnessed.
Here in England we have a tree that is at least 2000 years old.

The Ankerwycke yew

There may be yew trees in Britain that are older but the 31-ft wide yew ( Taxus baccata) found in the ruined priory of Ankerwycke in Berkshire has witnessed at least 2,000 years of history and myth-making. It is said to have been the spot where King John signed the Magna Carta in 1215 and is rumoured to be where Henry VIII conducted his first liaisons with Anne Boleyn.
