The construction of the 'new werk' was started in 1300. It was completed after ten years in 1310. The style matches the common norman tower type of the time. Contrary to some literature, the tower was build in this form from the beginning. The fire in the 1360s destroyed most of the wooden elements and had to undergo major reconstruction.

The original roof was made of lead, and was replaced by copper in 1474. This was again replaced in 1558 by a tiled roof and by a new copper roof following that. The copper was then used for military purposes in 1916 reconstructed later.

The original purpose was to host troops to defend the ships entering and leaving the Elbe from sea and beach pirates. The tower was also refuge for the farmers on the island during storm surges and survivors of shipwrecks over the centuries.[1]

The tower marked the most norther measuring point for the triangulation of the Kingdom of Hannover by Carl Friedrich Gauss[2] in July 1825. Parts of this triangulation net were depicted on the back of last series of the 10 Deutsche Mark note (1989–2001).

The tower of Neuwerk is officially Hamburgs oldest building. A church in Sinstorf is actually older, but only part of Hamburg since the Greater Hamburg Act of 1937.

The tower is protected under cultural heritage management since 1924 and the surrounding dwelling hill since 1971. It is used as guesthouse and restaurant.


A open coal fire beacon was build around 1644 as a navigational aid during night time. This required 1000 tons of imported Scottish coal a year starting from 1761. This coal contained more bitumen and burned much brighter than the usual German hard coal.[3][4]

The towers and beacons of Neuwerk (1825/1831)

The tower was only turned into a lighthouse on Dezember 20, 1814. The first lamp was made of 21 hollow wick oil lamps with parabolic reflectors and burned on colza oil and kerosene starting 1870. A fresnel lens of measuring a focal length of 700 mm was installed 1892 together with a five-wick kerosene lamp, to improve the brightness even further. This lens is still used today.[5] The lamp was again improved in 1908, to be first electrified in 1942. Electricity was needed to shut down the light quickly during the war. The kerosene lamp were kept in place as there was no emergecy power supply and upgraded to propane in 1949. The luminous intensity was stated in 1952 to be 5700 Hefner lamps (HK) 13200 seaside, 1000 for the green and 550 for the red light. The reach of the 1000 watt lamp was roughly 30 kilometers. Is could be seen from Heligoland und good conditions.[6] The classic electric lamp was replaced by a Halogen lamp in fall 2007.[5] On February 10, 2014 it was replaced by LED.

Although belonging to Hamburg, the lighthouse was operated by the Wasser- und Schifffahrtsamt Cuxhaven, which is responsible for the Elbe estuary. As the lighthouse was non-essential for shipping it was decommissioned on January 1, 2014 and turned over to the Hamburg Port Authority. On Februray 10, 2014 it was officially shut down after almost 200 years in operation and continues as a "private light" under the authority of Hamburg.The original light characteristic "Blk. (3) w. r. gn. 20 s 16–11 sm" was switched to a steady white lamp with a reach of barely 3 nautical miles.[5][7][8]

The original open coal beacon was replaced by the small lighthouse after the great lighthouse started operating and functioned together with him as leading lights. This allowed for safe passage from north-west over the Vogelsandsteert. The small lighthouse was torn down in 1909.[9]


Apart from the floors for the guesthouse for the Hamburg state guests, the tower is home to the warden, a restaurant and their personnel. The former teacher Heinrich Gechter initiated the use as a hostel for schools of Winterhude in 1920, which switched to the neighboring barn 1924.[10][11] The attic was also home the bird warden from the Verein Jordsand for many years.
