I’ve been editing Norham Castle. See http://www.openstreetmap.org/#map=18/55.72152/-2.15105
The wiki tells me that the correct way to map this is:
- A single area for the whole of the castle, tagged with “Historic:Castle” and “Name:Norham Castle”
- Individual bits of building/ruin as untagged areas
The individual bits of ruin are rendered as I would expect, but the perimeter, symbol and name do not appear.
I’ve also tried this as a multipolygon; that didn’t work either. I’ve since learned that a multipolygon is not appropriate anyway, as the buildings are not holes within the whole.
