Trivia: The tree in middle of the major road in Ealing, London - why?

In 1889, a circus was trooping down Ealing’s Castlebar Road, when one of its elephants died. It was too heavy to move so was buried where it fell and an oak tree was planted to mark the spot. This is why there is randomly an oak tree in the middle of a major road in Ealing

What does AI say?

I cannot verify the exact story you mentioned, as there might not be enough historical records available for such a specific event. However, there are known instances of circus animals, including elephants, being buried where they died. It is not unusual for trees or other markers to be placed on such burial sites.

Regarding the oak tree in the middle of a major road in Ealing, it is possible that the tree was there for a different reason, such as an old boundary marker or as a result of previous landscaping.

Ultimately, while the story you shared could be a local legend or an interesting anecdote, I cannot confirm its accuracy without more substantial evidence.
