This is how Tombland Alley looks today, an alley that runs behind St. George Tombland and comes out opposite the Erpingham Gate. The areas of raised ground is where the burials took place and they were once more contained than they are now with railings, some evident in the photo taken by the late great George Plunkett in 1936.
This image is from Percy Stimpson (1880-1948) and so would date to around the 1920 or 1930 period. The iron railings that were removed during the Second World War for scrap iron are still visible, and I think interestingly, so are numerous gravestones. It’s not quite clear to me when these might have been removed, but it appears to have been around the 1950s or 1960s.
