Rheinsberg - City of the brother of King Friedrich
Frederician Rococo began evolving with the acquisition in 1734 of the supremacy by the Prussian King Frederic Wilhelm I (1688-1740), and the subsequent rebuilding and new erections carried out on the plain Renaissance buildings (built after 1566) to transform it into the residence of the Prussian Crown Prince Frederic (1712 - 1786). The Unit Castle Rheinberg and Grounds provided considerable impulses for buildings and gardens in Berlin and Potsdam Sanssouci.
In 1736 already, the Crown Princely couple Frederic and Elisabeth Christine took residence in the South Wing of the Castle comprising the tower cabinet, where Frederic had his library set up.
Until 1744, the castle and grounds were completed by G.W. von Knobelsdorff, A. Pesne, Ch. F. Glume, and J. S. Sello. After Frederic II begin his reign, he offered the compound to his brother, prince Heinrich (1726-1802), who occupied it until his death and had the whole residence greatly expanded and in parts newly fashioned.
