There’s good news about the missing parish boundary marker which was located on Princes House and it seems that the building, and indeed the marker, is now in very good hands. Further information about this parish is at https://www.julianwhite.uk/norwich-history-by-parish-st-george-tombland/.
Andy from Princes House messaged me to say:
“The original design for Princes House from the early seventies was not the moribund architecture which you see now. The hard economic times saw the design diluted and we have played our part to add some interest and curiosity to our side of Princes Street.
You will be pleased to know that we are creating some art which will feature the Hungate St. Peter parish boundary marker which we have had professionally cleaned to remove the paint and cement splatter from it, while retaining its patina. We will describe the relevance of 1834 and the Poor Law Amendment Act and the historical boundaries referenced by the parish boundary marker. Along with this we plan on celebrating pictorially the local churches, those that are still with us and those that are not. It is our intention to have this up and displayed this spring.”
I think I might lead another walk when the work is completed.
