text: I found your other notes and am consolidating them all here.
  
  Forster Road should be visible if you zoom in fully -- it's certainly visible at https://www.openstreetmap.org/#map=19/51.59195/-0.07008&layers=N

  From Maps Me, you're actually editing OpenStreetMap data and in the OSM editors it's possible to move the map object and I've done that -- you may need to refresh the screen several times to pick up the updated map tiles. I can't move the note itself, but it's the map data that's important and notes disappear from most maps 7 days after resolving them.

  Concerning the classification, I can only say that OSM considers even local people to be tourists, hence galleries have to be mapped with the tourism=gallery tag, It's theoretically possible (but strongly discouraged) to invent new tags, but the result is that the data will not be found in relevant searches, nor will it get an appropriate icon on most maps.
