Why did it got rejected?

I thought it was a valid POI

Can you explain why you thought this would meet criteria? It isn’t obvious to me how this is a great place for exercise, exploration, or being social. It seems like it is just infrastructure, but I will allow that I may be missing context.

I thought that little fountains were accepted in the niantic criteria. But I was wrong

If you want to share a general location, some people on this forum are really good at looking around on the map to suggest things to submit.

Colle della Torre, Termoli.
I suggested most of the things i saw there besides the park itself

Is this the right area?

if that basketball court is not part of a school for under 18 year olds, that would be a good wayspot. There is a sign on street view, but i can’t read it.

Already submitted

The sign is for some building they are doing there
