Chiwan Left Fort, Military fortification in Nanshan District, Shenzhen, China.

Chiwan Left Fort is a fortification made of granite and brick in the Nanshan area with multiple gun emplacements along its walls. The structure overlooks Shenzhen Bay and shows a classic layout for coastal defense.

Chiwan Left Fort was first built in 1669, the eighth year of the Kangxi reign, as one of a pair of batteries flanking Chiwan harbour. In 1839 Lin Zexu rebuilt the Chiwan forts while strengthening the Pearl River estuary defences. The forts fell into disuse during the Guangxu reign, and only the left battery survives.

The fort displays Chinese military building methods from the Qing period, with walls and gun positions that remain visible today. You can see how soldiers once monitored the coast from these same spots.

The fort is accessible via a pathway that leads to several viewing points along the fortification. From these spots, visitors have clear sight lines across the bay and the city beyond.

The fort was built in 1669, not 1717, and no Japanese WWII modifications are recorded in the sources. After 1949 it served as a military sentry post, and in 1985 a bronze statue of Lin Zexu was erected beside it for the 200th anniversary of his birth.
