Living away, I haven't been to that part of town for a while, but in order there were the General Hospital, Town swimming baths and the old park, which was a great place for kids - overgrown woodland, which you can see in the background of the view in the film of the fishing smack unloading mussels.
P.S. I once sat on Hoppalong Cassidy's horse (Topper) outside the entrance to the General Hospital.
