Wellingsbüttel Manor is baroque manor house in Hamburg, which once enjoyed imperial immediacy (Reichsfreiheit). Wellingsbüttel was documented for the first time in 1296. In the early 19th century it was the residence and place of death of Friedrich Karl Ludwig, Duke of Schleswig-Holstein-Sonderburg-Beck, the penultimate duke, who was an ancestor 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 Grand 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 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.
Theobald Joseph von Kurtzrock erected the present manor house in 1750. In 1757 Georg Greggenhofer designed the gatehouse.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
