The lighthouse of Þrídrangar (Thridarangar) , south of Iceland, a few kilometers off the Westman Islands in the Atlantic Ocean.
It was built in 1939 and is considered one of the most remote lighthouses in the world. The constant crashing of waves against the rocks makes arrival by boat virtually impossible.
The Þrídrangar lighthouse sits 36 meters high on a rocky peak, accessible only from the air, by helicopter.
Surprisingly, both the lighthouse and the landing platform were built by a few daring climbers. They used a small opening in the rock to gain access to this extremely inaccessible location.
