Celle Castle (German: Schloss Celle) or, less commonly, Celle Palace, in the German town of Celle in Lower Saxony was one of the residences of the House ofBrunswick-Lüneburg. Celle Castle is based on a fortified wall tower (Wehrturm) with the character of a water castle, that guarded a ford over the River Aller. This first fortification, called Kellu, was built by a Brunonen count around 980 AD. Another forerunner of the castle, which may have been an extension of the wall tower, was founded in 1292 by Otto the Strict.
