I explored the town a bit using Google Street View, however most of it is from 15 years ago and I’m sure the town has changed quite a bit since then. So forgive me for not being super thorough, without actually walking the town this is about as good as I can do.
The first thing I spotted is a plaque on the wall in Plaza de la Constatucion which I don’t see on the Intel Map. However it is in the same cell as Paroquia San Juan Bautista so it would not show up as a PokeStop. However it could be useful for Ingress players and would give them (and possibly others playing other games like Pikmin or Peridot) something to hack/flowers/etc.
The second thing I spotted was a sign with a portrait of Charlie Chaplin on it. That might qualify as unique signage, if it’s still there. That sign certainly seems unique and if it still exists it might be something to nominate.
One idea that came to mind that you may know about in the community but I can’t find are shrines dedicated to saints. I live in Italy and there are sometimes small votive shrines to Holy Mary or to individual saints in public places. Those could qualify as places of worship. Here there are sometimes small shrines in the common areas of apartment buildings, or little statues where villagers gather to say prayers.
Another thing I didn’t see but might exist are religious frescos or wall art. There could be something unique on an older building that I simply didn’t find during my look on Google. I know in small towns in Italy these can often be found on old buildings, paintings of angels or religious scenes. Maybe you’ve spotted a small sculpture or bas-relief while walking in town. Those could potentially be great Wayspots.
Being in a small town, you likely know which cafes and restaurants are popular with locals and serve as a favorite social spot. I would suggest nominating one or more of those and really going into detail in the supporting information section of the nomination. If, for example, there is a cafe where everyone heads to on Saturday mornings, you could mention that. If a restaurant serves special local cuisine, tell the reviewers about it. If it’s where the kids go after school for snacks and cold drinks, talk about that. What may be deemed generic in a big city is actually special in a smaller town.
One more idea is to look around for heraldry symbols. I was looking on the municipal website and there was this page with descriptions of the heraldry of the town and region. If you spot something with those symbols it could qualify under the exploration criteria.
I hope this is maybe a little bit helpful. I saw the church, city hall, playgrounds and football pitch were all already in game, so the obvious stuff is already taken. I wish I could have found something that’s a real slam dunk, but I hope this will give some more ideas of places to look for.
