Pitchford tree house is certainly one of the oldest, if not the oldest tree house in the world.It was built by Shrewsbury wool merchants, the Ottley family, who bought Pitchford Hall in 1473.
It is not known exactly when the tree house was constructed, but, according to John Yates from English Heritage, it is at least 300 years old.
Its most famous visitor is said to have been Queen Victoria, who visited Pitchford as a 13-year-old princess.
