I did not know of this area until I came across this photograph of Westonville Terrace that was taken at the turn of the twentieth century, It was taken from Winter Street and at the top of the cul-de-sac is Weston Park. There is a photo on Picture Sheffield that I cannot use for copyright restrictions. That one was taken on 28th November 1966 but the houses were totally demolished soon after, to make way for the University of Sheffield's Geography building.
There was another road called Salisbury Terrace that was demolished at the same time but there is no record or photograph of the road. The following photograph is what replaced Westonville and Salisbury Terrace.
