Perched a top one of 4 rock pillars sticking out of the sea off Westman, around six miles from Iceland’s mainland, Þrídrangaviti Lighthouse is known as one of the loneliest lighthouses in the world. The remote lighthouse was built in 1938. At that time the only way to get to the top was climbing. Builders had to kneel down and stand on their back because there where nowhere to get a grip.
Nowadays, the lighthouse is accessible by helicopter and even features a small helipad.
