Ancient shipyard used by Zheng He may lie beneath construction site

Experts estimate that a construction site in Nanjing, Jiangsu province, where hundreds of shipbuilding tools have been unearthed, contains the remains of a shipyard that built vessels for one of China's greatest navigators, Zheng He.

The admiral lived from 1371 to 1433.

Last year, many iron anchors, rudders and shoes made from palm fibers were dug up at Yongning Street in the city's Gulou district.
