Neuwerk (3 km², 39 inhabitants) is a Wadden Sea island on the German North Sea coast. Administratively, it forms a homonymous quarter of the city of Hamburg, Germany, which is part of the borough Hamburg-Mitte. This quarter includes the nearby uninhabited islands Scharhörn and Nigehörn. It is located northwest of Cuxhaven, between the Weser and Elbe estuaries. The distance to Hamburg's center is about 120 km.
During low tide the island can be reached on foot or by horse carriages from Cuxhaven, at other times by ship.
The smaller islands Scharhörn and Nigehörn are bird sanctuaries, closed to the public. All three islands and the Wadden Sea around them form the Hamburg Wadden Sea National Park.
The oldest existing document that mentions Neuwerk is a Frisian contract of 1316, where its old name Nige O is used.
Since the Elbe river was vital to the Hanseatic League's member Hamburg, in 1299 a 35 meter tower was built as lighthouse and protection against pirates. The lighthouse existing today was built around 1300 and was originally uaed as a watchtower. It is Hamburg's oldest existing building as well as Hamburg's last fortification.
HMS Proserpine (1777) stranded in thick ice and snow February 1, 1799 on the Scharhörn Reef, about 6 miles from Neuwerk. Among the 187 crew and passengers was the British envoy Thomas Grenville en route to Berlin in secret misson. 14 people died during the escape from the wreck over then wadden sea and ice to Neuwerk. In a repeated attempt to retrieve bread from the vessel a few days later a small party of five got trapped aboard the crushed remains of the frigate and floated back to the open sea. 36 hours later the Proserpine stranded again near Borkum, where they reached safety again and the wreck remained.
Due to the Greater Hamburg Law Neuwerk became part of Prussia in 1937, and thus after World War II it was given to the new state of Lower Saxony. In 1969 Hamburg waived older rights on harbour estate in Cuxhaven in favour of Neuwerk and Scharhörn.
In the early 20th century, tourism became important for Neuwerk.
On 31 December 2007, Neuwerk quarter had 39 inhabitants, 26 female and 13 males. 11 were resident aliens.
