Fenway Park?
That is what all the mens rooms looked like at Fenway until twenty years ago. Until is was finally remodeled.
I was in Sorrento, Italy and they had a trough carved out of solid stone. Literally, carved into the side of the cave/rock face. It probably drained into the Med.
Marshfield Fair in Massachusetts. Town fair but it was the size of a county fair. Good sized midway, 4h, local crafts, horse racing with betting, demo derbies and the Chitwood Bros stunt driving shows.
I’m sure it’s all different now in commiechusetts.
