Thridarangar Lighthouse stands on a rocky cliff in the middle of the Atlantic Ocean in southern Iceland, just a few km off the coast of the Westmann Islands.
Built in 1939, it is the most isolated lighthouse in the world, today only accessible by helicopter.
The overwhelming impact of the ocean waves violently crashing into the cliff prevents the lighthouse from reaching it through any type of boarding.
A true fortress, perched at a height of 36 meters on top of a steep and dangerous rock, and accessible exclusively from the sky.
