This is listed as a general store on Google Maps, so that could have caused the rejection if this is incorrect. It does not appear that Google Maps has been updated to show that this is a government meeting place.
You are welcome to appeal the rejection and explain that there is no general store here, if incorrect on Google Maps, and further explain why this meet criteria. If you can find any links online that note this is a government meeting place also, that would be helpful. We get 2 appeals every 15 days.
It’s not very helpful to reviewers or even staff to say “Hey, there isn’t a sign marking this as a cultural center, but I swear that it is.” You have to provide proof that is it, and so far, that hasn’t been provided. The car out front also doesn’t make for the best photo, even though the license plate isn’t shown, but it doesn’t help make it stand out. Keeps things like this in mind for future nominations.
