Unearthed aristocratic architecture in Chengdu, capital of Sichuan, is likely the site of the State of Shu (1046-316 BC), an ancient state of the Three Kingdoms Period in what is now Sichuan, southwestern China, according to the Chengdu Cultural Relic Research Institute, Sichuan Daily reported on Aug. 22.

Early in 2013, a 2,000-year-old stone rhino was unearthed near the Sichuan Grand Theater in Chengdu. A large number of Han-period artifacts were also found, said Yi Li, an associate researcher.

Archeologists were amazed by the eaves tiles coated with vermillion—a symbol of royalty. Moreover, a terrace and a large amount of money including Wuzhu bronze coins were found at the site.

The new discovery may help uncover and locate the imperial palace of ancient Shu Kingdom.
