...and whose door is this?

..... it is a side door at Canterbury Cathedral. A poor photo as the angle of the sun caused shadows on one side. The door was opened at one stage and l asked the lady if she could keep it open for a minute so l could get a better photo - the answer was no and the door was closed.
Looking at the door l can see the repairs that were carried out in 2017 to some of the wood work; carbon dating on some of the timbers of the doors reveals they date back to around 1100.
