The Great Granite Bowl in Berlin's Lustgarten, which is located in front of the Altes Museum, has a diameter of 6.91 meters and weighs approximately 75 tons. With a circumference of 691⁄7 feet, it is considered the Biedermeier Wonder of the World and is the largest bowl carved out of a single stone in existence. Initially commissioned by Prussian King Frederick William III, the granite bowl was placed in the museum's rotunda.
