Egelsee, Artificial lake at Wartberg, Stuttgart, Germany.

Egelsee is an artificial lake in Stuttgart's Wartberg hollow, built for the IGA '93 garden show. Its long rectangular basin ends in two circular ponds: the Kugelsee with a sphere fountain to the west and the Fontänensee with a water organ to the east. The north bank is lawn with hornbeam cabinets, while the south bank has wild perennials and a rock fountain.

The water system was built from 1992 to 1993 as part of the International Garden Show 1993. Sculptor Hans Dieter Bohnet shaped the project with his water sculptures and design elements.

The lake is one of the Kunststationen built for the International Garden Show 1993 and kept afterwards. Its water features, including the ball fountain and the water organ, run on a computer-synchronised choreography. Sculptor Hans Dieter Bohnet also created the Kunststationen Unter den Stangen and Im Keuper on the Wartberg slope.

Reach the lake from the Löwentorbrücke tram stop via the ramp to the Bombaysteg footbridges, then take the left branch to the viewing bastion. Both this route and the path along the source streams are suitable for wheelchair users. Bus line 57 stops at Höhenfreibad.

Multiple streams converge at Kunststation Grottenloch and flow through cascade-like basins called Krebsschwanz before reaching the main lake. This hidden corner reveals the clever water engineering that feeds the entire system.
