Summary

DescriptionSuSongClock1.JPG
English: Su Song's Water Clock (?).

This picture is a scaled model of Su Song's water-powered clock tower.
The original clock tower was 35 feet tall. It was a 3 story tower with an armillary sphere on the——roof. And a celestial globe on the "third floor."

This picture was taken in July 2004 from an exhibition at Chabot Space & Science Center in Oakland, "California." The quality of the picture is not ideal. Because flash photography was not allowed.
