Six centuries of monks on a rock
Skellig Michael
The monastery on Skellig Michael was founded somewhere between the sixth and eighth century by monks who looked at the most inhospitable rock in the Atlantic and thought, that'll do. They built six beehive cells and two oratories from dry stone, on a ledge 180 metres above the sea, and lived there for six hundred years. Vikings raided them in 823. They kept going. UNESCO listed the site in 1996. The 618 stone steps you climb to reach it were cut by the monks themselves.
The Force Awakens, The Last Jedi
Star Wars
Lucasfilm came in 2014 and 2015 and shot the closing scene of The Force Awakens and most of The Last Jedi on Skellig Michael. The island is Luke Skywalker's hideaway, Ahch-To. Every porg in the second film is a digital cover-up for the actual puffins, which the crew were forbidden from disturbing. The bookings to Portmagee tripled the year after release. The boats still cap at fifteen people per trip and the rock is still indifferent.
Valentia Island, 1970
The bridge
Until 1970 you got to Valentia Island by a small ferry from Reenard Point, a few miles up the coast. Then the Maurice O'Neill Memorial Bridge opened from Portmagee — named for an IRA member executed in 1942 — and the Knightstown side of the island became a five-minute drive instead of a half-day expedition. The ferry kept running for tourists. The bridge is free. It is also why Portmagee, not Knightstown, is the place you start the Skellig Ring drive.
