Lophelia Pertusa – Trondheim Fjord's Living Cathedral
To breathe underwater is one of the most fascinating and peculiar sensations you can imagine.
The world’s most unique coral reef awaits you in Trondheim Fjord.
While coral reefs along Norway’s coast are usually found at depths of 200-400 meters, Trondheim Fjord breaks all the rules. Here, Lophelia Pertusa corals flourish in the shallowest water ever documented – so shallow that you can reach them with standard diving equipment. Skarnsundet actually holds the world record for the shallowest occurrence of the stone coral Lophelia Pertusa, a miracle of nature that attracts researchers from around the world. This makes our fjord a living laboratory where you can experience something that exists nowhere else on the planet.
An underwater ecosystem of indescribable richness.
Lophelia Pertusa coral reefs are far more than just beautiful structures – they are the foundation of one of the ocean’s richest ecosystems. Over 700 different species have made these coral reefs their home, many of them found nowhere else on Earth. Tauterryggen, which was protected as a marine protected area in 2013, and the proposed protected area in Skarnsundet, represent some of Norway’s most valuable marine habitats. When you dive here, you witness a complex network of life where each organism plays its unique role in maintaining this fragile yet resilient underwater universe.
