Stack-Fountain of Lustgarten
The impressive granite carving in the Lustgarten square, near the front of the Altes Museum, is certainly worth a visit. It was carved in the mid-nineteenth and is almost 7 meters in diameter and weighs 70 tons. At the time it was the largest single piece of granite in the world. It was intended to decorate the interior of the museum but it was too heavy to move inside! So it remained in the same place where it was carved.
