The 20.1 m high tower was the last in a long series of lighthouses built in Germany from prefabricated steel elements (tubbing) of the Isselburger Hütte. The tower carries the upper fire for the southern driveway and the beacon for the northwest driveway to the Helgoland port facilities.
The Unterfeuer is a 10 m high steel pipe mast, about 120 meters south of the lighthouse in the Watt.
Both beacons have been preserved several times, most recently in June 2007.Source: Wiki
