Duplicate or not
There is a park in my home town that stretches over 2 blocks. Each section has 2 sets of concrete benches planted in the ground with chess boards built into them (so 4 sets of chess benches in total) and each set is in its own location in the park, relatively far apart from each other.
Are these still clasified as duplicates or can each individual set be a POI? Keep in mind they are not in close proximity like a playgrounds structures.
