The Leineschloss, situated on the Leine in Hanover, Germany, is the former residence of the Hanoverian kings and the current seat of the Landtag of Lower Saxony. The first building on the site was a Franciscan friary, constructed in about 1300, which was abandoned in 1533 after the Protestant Reformation. In 1636, George, Duke of Brunswick-Lüneburg, began construction of the palace on the site as his residence. In 1742 the north-west wing was renewed.
