Þrídrangaviti Rock Islets are a series of three small, rocky outcrops located off the coast of Iceland’s Westman Islands. These islets are home to one of the world’s most isolated lighthouses, which is perched on the tallest of the three rocks. The site is one of the most extreme examples of human isolation and ingenuity.
The lighthouse was built in 1937 by a team of Icelandic builders who had to work in treacherous weather conditions to construct the building. The tower stands at 43 feet tall and provides vital navigation guidance for sailors navigating through the dangerous waters of the Atlantic Ocean surrounding the Westman Islands.
One of the reasons that the Þrídrangaviti lighthouse is so unique is its isolation. Towering above the waves, it is only accessible by helicopter or by boat in calm conditions. The lighthouse is so remote that it can only be accessed by a crane which lowers supplies and personnel onto the rocky outcrop.
The Þrídrangaviti lighthouse also has an unusual piece of history. In 1984, the lighthouse was struck by a massive wave which dislodged the entire lantern room from the tower. The lantern room continued to function for several days while floating in the ocean, but it was eventually rescued by a helicopter.
The isolation of the lighthouse has led to some remarkable stories of human perseverance. One such story involves the lighthouse keeper’s assistant who was once trapped on the rock for three weeks after being unable to leave due to stormy weather conditions and the remote location. Despite being isolated, the assistant managed to survive by collecting fresh rainwater, eating seabirds, and scavenging supplies from the maintenance shed.

In addition to being a unique landmark, the Þrídrangaviti lighthouse is also home to a variety of seabirds which nest on the cliffs surrounding the rocky outcrop. The harsh environment provides a home for puffins, fulmars, and guillemots which are able to thrive in the challenging conditions.
