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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
