Yes, no province can have more than four sites, and many sites are terain limited (most underwater ones are underwater only, and vice versa, though many have other weirder restrictions)

P.S. Can you get the Caspar of the cave event (adds E1 site) in a province w/ 4 sites? wouldn't think so but you never know... hard to prove a negative.
