In 1785 a 35-meter tower was erected with an open fire. In 1805 a lantern replaced the fire and in 1838 a mirror was added. Then in early 1842 a flashing light replaced the fixed light, and a lightship was towed to a station of the Knobben, off Anholt. Around the mid-19th century there was also a floating light stationed several miles out from the lighthouse, near the end of the several miles long reef. This floating light operated from May to December. Today's tower dates to 1881, at which time an oil lamp replaced the fire. At one time there was also a beacon fire in the middle of the east coast of the island, but that has disappeared. The present Anholt Fyr (lighthouse) belongs to the Danish Maritime Safety Administration and has the status of a protected historical landmark.
