I'm assuming that your note meant you thought it should be in the map.

If that's the case, adding more information is definitely useful. While we shouldn't just 'tag for the renderer', more info does sometimes mean it renders when you think that will be useful.

Eg, it could have heritage tags that link to the scheduled monument listing

Tagging system for England:
https://wiki.openstreetmap.org/wiki/Key:heritage#England

Listing information
https://historicengland.org.uk/listing/the-list/list-entry/1020768

Does that help at all?
