|Namespace for features that have been demolished, without any traces left.|
|Used on these elements|
taginfo count: demolished:*
|Status: in use|
|Tools for this tag|
|This tag page describes a namespace rather than a simple tag.|
However, prior to 12/2014, it may have been used for things like ruins=* or when the feature is almost but not completely invisible.
There is some dispute over the use of this and other lifecycle tags, with the main argument being that OSM is for features existing on the ground. This tag, however, is useful for preventing other mappers from inadvertently remapping demolished features that are still visible in aerial/satellite imagery currently available in OSM editors. (The note=* key may be a slightly less controversial alternative for this purpose.) Use sparingly.
See nonexistent features for more general discussion of mapping no longer existing features.

Use abandoned:railway=* instead!
