Some of the palace's most beautiful rooms can be admired in the Neuer Flügel (New Wing), which reopened to the public in December 2014 after a two-year restoration of the approx. 150 meter long facades. Inside you can visit the lush private living quarters of Frederick the Great and the less pretentious but stylish apartments of Frederick William II. Frederick the Great was an admirer of French painting and a large part of his collection of eighteenth-century paintings is on display in the private rooms. One remarkable painting shows Napoleon leading his army through the Swiss mountains. It was brought here from Paris after Napoleon's defeat at Waterloo. The most impressive rooms in the New Wing are the two large halls: the Weisser Saal (White Hall), a magnificent dining room, and the Goldene Galerie (Golden Gallery), a 42-meter-long (138 ft) ballroom decorated with mirrors and gilded Rococo-ornaments. Also don't miss the collection of marble statues from the nineteenth century, on display in the vestibule of the New Wing.
