In my part of the world there is a famous historic place called “Dacre Cottage”. It gets lots of visitors. It is not on a public road. You have to walk along one of several walking tracks to get to it. It is right on a beach (which is also not named in Google Maps).
It is located at 36°39’29.7"S 174°43’39.5"E, and you can see it in the Google Satellite imagery.
I have tried added this place many times over time, as I think it would help other people planing on visiting it. I can usually add places ok, just not this one. I find it very frustrating.
I’m 99.99% confident nothing can be done about this, but decided I would try asking here just in case.
