About Løgstør Grunde Forfyr Lighthouse
Built in 1908, the Løgstør Grunde Forfyr stands as a square, white tower measuring 9 meters in height. The structure is characterized by a rectangular building featuring two square lantern houses, positioned at opposite ends. This lighthouse emits an isophase red or green light on a 4-second cycle, with a geographic range of 10 nautical miles. It is located on the south side of the Limfjord along Havnevej in Løgstør. The site is accessible to the public, but the tower itself remains closed.
Why it matters: This navigational aid is essential for guiding eastbound ships through the narrow Aggersund channel, a critical passage in the Limfjord leading to Ålborg. Its distinctive dual-lantern design provides precise directional guidance for safe transit.
