Old shipwreck recovered from Yangtze riverbed

"The project has provided a Chinese example, Chinese model, and Chinese experience for the global protection of underwater cultural relics," he said.

In the coming days, another vessel will take the shipwreck to the former site of Shanghai Shipyard in Yangpu district where it will be examined and studied. The ship has been described by the heritage administration as "the largest and best-preserved sunken wooden sailboat in China's underwater archaeological findings, with a huge number of cultural relics on board".

Fang Shizhong, director of the Shanghai Cultural Heritage Administration, said that the discovery of the ancient boat "proves Shanghai's position as an important shipping and maritime commerce center for East Asia and even the whole world."

In 2015, an underwater archaeological investigation in the Hengsha area detected a sunken iron vessel via sonar scanning technology, local media reported.

The iron warship was named the Yangtze River Estuary No 1 Ancient Vessel. As archaeologists expanded the scope of their scan, a wooden vessel was found north of the warship and named the Yangtze River Estuary No 2 Ancient Vessel.

A total of 31 cargo chambers were detected in the No 2 vessel, with its main structure almost intact, including the prow, bollard, port side and starboard.

Items have already been retrieved from four selected chambers, including ceramic objects made in Jingdezhen, Jiangxi province. Also found on the vessel or scattered nearby it were purple clay objects, pots made in Vietnam, pulleys, cables and construction material.

Chu Xiaobo, director of Shanghai Museum, said in a CCTV livestream that the shipwreck contains so much historical information that it is equivalent to the long scroll painting Along the River during Qingming Festival, a revered painting that depicts daily life during the 11th and 12th centuries in China.
