Bridrangar Lighthouse, Iceland.

The whitewashed lighthouse is perched atop the tallest of the rocky cliffs, which stretches an impressive 120 feet upward. It’s off the coast of the Westman Islands, which themselves are about 4.5 miles from mainland Iceland. Because of its isolation, some on the internet have jokingly dubbed the beacon a haven for introverts.

The remote lighthouse was built right before the dawn of World War II. Constructing this lonely lighthouse was no easy task, as helicopters had yet to take to the skies when the work began in 1938. Builders scaled the cliffs to reach the pillar’s pinnacle, laying out the groundwork by hand. They faced slick rocks, rain, and fervent winds knowing that one slip could send them plunging into the frigid North Atlantic Ocean that thrashed and splashed below.
