My primary school was behind the camera position and I used to catch the bus home by those trees on the left. As mentioned, this used to be the main route (A257) out of Canterbury heading for Sandwich. Lower Chantry Lane which is in the distance was a very narrow lane but it was widened late 50s/early 60s to become the main route.
Canterbury Hospital was built on the left, in front of St Augustines Abbey. When the new hospital was opened, this building became a Technical College. That has since been demolished and is now the site of the new St Augustine's Museum and Visitor Centre.
