BUR #19975 has been approved by @evazion.
deprecate landmark
There's a wiki-less tag (at least until now) called landmark which seems to emcompass various real life landmarks like Statue of Liberty or Eiffel Tower. However, the tag is sporadically used for this, and is used for any building that is "eye-catching" enough to stand out in the image.
Given that we are now tagging each individual notable landmarks (both real and fictional), I don't see the reason for this tag to exists given that each individual building is self-descriptive enough, so I suppose it should be deprecated.
