Thanks JT I'll narrow it up later.

But first, I have started on the chapel. For this map, I am making it a bit bigger than I anticipated and I am using the (reduced) floorplan of Siena Cathedral in Italy. This is still at conceptual stage - the black and white tiles each are 5 feet, so the entire chapel is 130 feet/40m long which seems quite big to me but perhaps is the right size (?) for a chapel rather than a cathedral.
