Not accepted wayspot

I added a wayspot and it was declined with the reason that is was private/farm/other.. this is not the case at all. As I have described in the description it is a part of a museum, and it even has a sign on it to say so there is also a public hike 2 meter from it. How can this be declined with this reasons?

Can you share the full nomination? :)
It makes it easier to comment on it.
I would accept this nomination.
Part of a museum, nice story... Could be fine. I'm missing the description and rest of the nomination, but a first look it could be a nice waypoint.
You could appeal, or resubmit.
Looks like same cases at this time, there's some bot reviewers at this time because too many reject criteria without reason. Here's some real detail : https://community.wayfarer.nianticlabs.com/discussion/46708/coffee-shop-sign-its-a-license-plate-invalid-and-fake#latest
Anyway, this object can be accepted too.
I would not call that a "building" as you would see in the city. I call it a cute shed which is going to take a lot more convincing.
The description could be improved by stating the exact year it was built because "very old" is subjective. Mention the museum name. For instance, there is a "very old" Bayou Bend mansion on 13 acres that is owned by the Museum of Fine Arts, Houston (MFAH).
But I would skip this and look for more significant point-of-interest (POI) around the museum park.
