The relics were looted from Beijing's old Summer Palace, also known as Yuanmingyuan, by French and British troops in 1860 before finally being returned to China in 2003.

A visitor takes a photo of the monkey head at the Hangzhou Poly Dongwan Exhibition Center on Wednesday, August 20, 2008.

The pig, ox, monkey, and tiger heads, representing some of the Chinese astrological animals, together formed part of the famous horological fountain which was located outside the Hall of the Calm Sea in the garden of the old summer palace.

The exhibition is free of charge and will continue until August 25.
