The Twelve Old Summer Palace bronze heads are a collection of bronze fountainheads in the shape of the Chinese zodiac animals that were part of a water clock fountain in front of the Haiyantang building of the Xiyang Lou area of the Old Summer Palace in Beijing. Believed to have been designed by the Jesuit Giuseppe Castiglione with fountains engineered by Jesuit Michel Benoist for the Qianlong Emperor, the statues would spout out water from their mouths to tell the time.
