Royal Portrush will provide players at this week’s Open Championship with the usual tests that come with a standard links golf course: pot bunkers, thick rough, firm fairways, and, of course, wind and rain. But you can add something else to that list: storm shelters. Well, one storm shelter, at least.

There’s a tiny one left of the green on Portrush’s picturesque par-4 fifth hole and, apparently, it’s in play. Very much in play.

Paul Casey found this out (fortunately) during a practice round, disappearing into the dark space and expertly escaping by chipping onto the green. Check it out:

Well, that’s one way to avoid standing out in the rain. Savvy move, Paul, but it’s still a pretty bizarre sight to see on a golf course. Fingers crossed we see more of it once the tournament actually starts.
