Granite bowl

Texte de Wikipédia en anglais, en attente de traduction.

The Great Granite Bowl in Berlin's Lustgarten (German: Granitschale im 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 (approximately 21.7 meters), 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. Since it proved to be larger than originally planned, it was eventually installed in front of the museum. The bowl, which the artist Johann Erdmann Hummel represented in a number of sketches and paintings, was not only regarded as a technical marvel at the time but also as a "patriotic symbol," "cult stone," and "myth."
