The Upended Sugarloaf (in German: Der umgestülpte Zuckerhut) is a half-timbered house in the city of Hildesheim in the federal state of Lower Saxony in Germany.

In the 1980s, the historic market place of Hildesheim, which had been destroyed in 1945 as well, was reconstructed in the authentic style using old photos and construction plans.

From 2000 on, the Altstadtgilde, a private association dedicated to the embellishment of the city, started collecting funds to reconstruct the Upended Sugarloaf and bought the piece of land where the building had stood before the war.

Many inhabitants donated money for the project, as the Altstadtgilde intended to give the building to the City of Hildesheim as a present.

The City Council, however, hesitated a long time before accepting the present, but finally the building permit was granted on 4 February 2009.
