The palace's oldest section, the Altes Schloss, is an extravaganza in stucco, brocade and overall opulence. Highlights include the Oak Gallery, a wood-panelled festival hall draped in family portraits; the lovely Oval Hall with views of the gardens; Friedrich I’s bedchamber, with the first-ever bathroom in a baroque palace; and the fabulous Porcelain Chamber, smothered top to bottom in Chinese and Japanese blue ware.
