Wellingsbüttel Manor is a former manor with a baroque manor house in Hamburg
, which once enjoyed imperial immediacy (Reichsfreiheit). Wellingsbüttel was documented for the first time on 10 October 1296. Since 1937 it has formed part of the suburbs of Hamburg as the heart of the quarter of the same name, Wellingsbüttel, in the borough of Wandsbek.
The owners of Wellingsbüttel Manor from the beginning of the 15th until the early 19th century were consecutively the Archbishops of Bremen
, Heinrich Rantzau, Dietrich von Reinking, the Barons von Kurtzrock, Hercules Roß, the Jauch family, Cäcilie Behrens and Otto Jonathan Hübbe. In the early 19th century it was the residence and place of death of His Serene Highness Friedrich Karl Ludwig, Duke of Schleswig-Holstein
-Sonderburg-Beck, the penultimate duke, who was an ancestor inter alia of the present-day British royal family.
Wellingsbüttel Manor was elevated to the status of a Danish "chancellery manor" (Kanzleigut). It was then acquired by the Great Burgher of the Free and Hanseatic City of Hamburg Johann Christian Jauch junior (1802–1880), becoming a country estate of the Jauch family.The manor house is together with Jenisch House
(Jenisch-Haus) one of Hamburg's best conserved examples of the Hanseatic lifestyle in the 19th century and jointly with the manor gatehouse a listed historical monument. The estate is located on the banks of the Alster River in the middle of the Alster valley (Alstertal) nature reserve.
Since 1957 the Alstertal Museum ("Museum of the Alster Valley") has occupied the, seen from the entrance to the manor, left wing of the gatehouse. The museum, set up by the Alsterverein e.V., a society founded in 1900 for the preservation of the Alster Valley, presents a number of exhibitions, both permanent and changing, on aspects of the area of the Upper Alster.
The permanent displays cover Wellingsbüttel, not only the estate and manor house but also the old village, including (with the permission of the Danish Crown) the only copy of the 1810 deed of enfeoffment of the Duke of Schleswig-Holstein-Sonderburg-Beck.
