Hello,
First off, when you nominate something, you are nominating it to be a Wayspot to be added to the Lightship map. All Niantic games are able to use the Lightship map to choose game locations, but each game also have their own density rules.
As for this, I do not know if this will even be accepted by both the review community and Niantic, as it just appears to be a wall, nothing unique. Even if you note that it is a popular meeting spot, I really don’t see anything that makes it distinct. If it is a historical wall and you are able to provide more informaiton about said history, like a plaque or sign on it, that would be a better thing to nominate.
Being in rural areas can be tough to find good Wayspot nominations, but we do have a good forum thread with a lot of tips that you may want to check out.
I’d also recommend reviewing Wayspot criteria, to learn what is and isn’t acceptable.
