Pazhou Island, formerly Whampoa Island, has a total area of 15 km2 (5.8 sq mi) and is the site of Pazhou Pagoda. Its eastern bay was formerly the chief anchorage for ships participating in Guangzhou's foreign trade. Traders from the "Southern Sea", including Indians, Arabians, and most Europeans, were required to keep their ships at Pazhou while smaller craft ferried goods to and from the Thirteen Factories area of Guangzhou's western suburbs. Traders rented storage for ships supplies and repair shops on Whampoa Island. Images of the anchorage were a common theme in 18th-century art.[2][3]
