It was built for Count Hans Caspar von Bothmer to designs by architect Johann Friedrich Künnecke in 1726–32.

[3] Bothmer was active as a diplomat in service of the Electorate of Hanover and lived for long periods of time abroad, notably in London.

Among other things, he played a role in helping his employer secure the British throne as George I of Great Britain.

Hans Kaspar von Bothmer (1919–1946), nephew of the last owner, had stayed in the castle and worked in the hospital as a nurse until his death.

The scope of the construction work was enormous: 740 tons of concrete alone were poured into the new foundations, project manager Siefert notes.

It was not only the overall design which was inspired by foreign examples but also the details: originally, the palace had sash windows, betraying a direct British or Dutch influence.

[5] After the renovation of the castle, it today houses a museum which occupies more than 20 rooms, and is focused on the life of Hans Caspar von Bothmer.
