The dolphin fountain is located in front of the idyllic old orangery garden in Belvedere Park. The fountain has a circular basin which is set into the ground and only has a bulging edge around 20 cm high above the surface of the water. The water rises within the fountain column to a round water bowl, over the edge of which it overflows into the fountain basin. Three dolphins swimming down decorate the fountain column, which they hold with their tail fins. The creator is unknown.
