You could just call them windows, but when there's a view of the ocean, you could also dub them portholes.
Old Mill Point has quite a number of them, scattered about. Some are round, some are octagons, some are slatted - one is even an elongated oval. But they are all over the neighborhood.
Your mission - should you choose to play - is to discover where in the Point these portholes lie. All are visible from the road, although I suspect some folks have hidden round windows that only they can use.
As always, good luck!
