Blüse Neuwerk
The Blüse Neuwerk (also called Feuerblüse) was built in 1644 by the city of Hamburg on the island Neuwerk. Together with the other beacons and the Great Tower Neuwerk, which was just a fortification at the time, it was the first lighthouse in the Elbe estuary and, after the Blüse Helgoland (1630) and Wangerooge (1631), the third on the German North Sea coast. The wooden frame was remarkably high for the time and was erected in the northwestern shore of the island. When its position was threatened by erosion of the shoreline at the beginning of the 19th  century, it was replaced by a wooden lighthouse behind the dyke in 1814. The bearing together with the 1310 erected Great Tower Neuwerk (lighthouse since 1814) led sailors to the Schartonne near Scharhörn. The northern daymark, somewhat further seawards, obscured the fire of the Blüse on that bearing. Olaus Magnus already depicted a lighthouse in 1539 on Neuwerk in his Carta Marina, however such a mark is still missing on Melchior Lorck's much more detailed map of the Elbe from 1568. Construction. A three-part ladder under the platform led to the so-called guard house, a small room  for the warden. On the platform itself stood the large fire grate. To protect the wooden structure from the open fire, a layer of clay, sand and a brick pavement on top covered the wooden planks. A replica of the Blüse Neuwerk stood from 1979 to 1994 in the German Maritime Museum in Bremerhaven. Operations. In the beginning the coal fire was only operated between September 29 and March 31, from the beginning of the 18th century the season went from September 14 to April 30, and starting 1735 from September 1 onwards. For the year-round operation from 1761  onwards, 1000 tons of hard coal were needed. Hamburg imported the coal directly from Scotland until 1771, which produced a brighter fire than hard coal from Germany. The coal was then sourced from Hamburg. Hamburg built its own coal galiote and maintained a coal port near the beacon. From 1673, the ship also supplied hard coal to the Hamburg-operated Blüse on Helgoland. The warden ran the Blüse together with two servants and initially earned only 30 talers a year, from 1656 50 talers, from 1692 530 Lübische Mark and from 1695 650 Lübische Mark. The operation was suspended from  1807 to 1813, but there were further interruptions due ice drift and when the wooden structure caught fire in 1724 and 1794, despite having extinguishing water on the platform all the time.
