Cool cool, I've deleted the old area at the moment as now that there's a POI it should mean you're searchable on all the OSM based map applications. You can always upgrade to an area again in the future.

From here I'd recommend adding more tag info to the point you've dropped. Access information is particularly important to add to the map but here are some suggestions for tags you could add:

addr:country=GB, addr:housenumber=*, fee=no, contact:phone=*, contact:email=*, wheelchair=*, amenity=toilets, toilets:wheelchair=*, shop=gift, internet_access=wlan, description=*, ref:wikidata=*

I might also suggest collecting street level imagery through Mapillary or Karta View of the surrounding area as then other mappers will be able to map the location more accurately and support you with mapping.

Best of luck!
