????The Site of Deji Gate is the archaeological evidence testifying to the principal distribution center in the international sea-river-inland trade system of ancient Quanzhou. Deji Gate was the south gate of the ancient city of Quanzhou neighboring Jinjiang River and was built in 1230 (the 3rd year of the Shaoding period of the Southern Song Dynasty). The remnant city gate is a polygonal structure stretching 36.50m from south to north and 49.10m from east to west, with a perimeter of 171.20m and an area of nearly 2,000 square meters. The remaining site includes granite slabs in irregular shape and deserted stone components. In ancient times, merchant boats or local people reached the river dock from the sea, then entered the south gate of the city for commodity distribution and transaction. Over ten stone structural elements of Islam, Nestorian Christianity and Hinduism, dating back to the Song and Yuan dynasties, have been unearthed beneath the foundation of the gate site, which displays the peaceful coexistence of diverse religions. It fully exhibits the profound tradition of the port construction and management system of the Chinese Empire and bears a unique testimony to the prosperous maritime trade and the heyday of cultural exchanges in Quanzhou.
