This is a photo from the sixteenth century UK map in the Hall of Geographical Maps.
It’s interesting to see the names that the Italians at the time thought were the main places in Norfolk, we have Lyn (King’s Lynn), Cromer (I assume that’s Cromer, even though it’s in the wrong place) and Brandonferi (which I’m assuming is Brandon). Ah, since writing this, I’ve realised that the old name for Brandon is Brandon Ferry, so that’s what that is….
I don’t know what Pienan is, maybe Dereham, but there’s no Norwich on the map. There is a Norduico to the right-hand side and that appears a few times in medieval texts, but it doesn’t seem to be Norwich.
