Useful combination

ruins=yes

=yes is used in conjunction with a tag representing a structure to indicate that the structure is in ruins, e.g. historic=castle + =yes or building=yes + =yes

Notes:

Most data consumers don't evaluate the tag =yes and thus handle the structure as it were intact. It is especially problematic for features such as amenity=hospital where =yes would be a trolltag. For this reason, an unknown part of mappers advise not to use =yes.^[1] As an alternative, historic=ruins together with a =* sub-tag is often used for historical ruins (see section Sub-tag of historic=ruins below) and the lifecycle prefix ruins:* for non-historic features. Though for some features, such as castles - also a ruined one fulfils very similar function (tourism attraction) so =yes is not always a very big problem.
Some mappers use =yes for structures that are still recognisable for what they once used to be, and historic=ruins or ruins:* for structures that are no longer recognisable for what they used to be (e.g. where only the foundation walls are still visible).
