The Belvedere at Charlottenburg Palace in Berlin is a charming little construction built in 1788, topped with a dome and adorned with a group of youths holding a flower arrangement on its exterior. Today, the Belvedere houses a fine collection of porcelain. Additionally, the rooms in the Belvedere were once used for meetings of the secret order of the Rosicrucians, of which Frederick William II was a member. Inside the Neuer Pavillon at Charlottenburg Palace, designed by architect Schinkel for Frederick William III, visitors can admire a small exhibition of paintings, including works by the romantic artist Caspar David Friedrich.
