is there a way to get demolished historic buildings rendered? I’d like to map a number of former city gates (there is nothing left of these buildings), because it would be interesting to see where they had been existing once. I created single nodes with “demolished:building=yes” and “historic=city_gate”. However, these nodes to not show in www.openstreetmap.org. Is there a recommended way to get an icon for such buildings, which do not exist anymore but are historically interesting?
OSM maps what is visible on the ground. Tagging the former location of a demolished building as the building itself is wrong. Adding your own tag “demolished:building” has no effect whatsoever as it is not recognized by any renderer or data user. You have tagged buildings where none exist.
