Changmen battery, Military fortification in Fuzhou, China.

Changmen Battery stands on Dianguang Hill in Changmen village, Guantou town, Lianjiang county, on the north bank of the Min River estuary opposite Jinshan. Its main fort is a circular rammed-earth wall 12 m high, 1.5 m thick and nearly 300 m around, enclosing 50 mu. Five German- and British-made guns were mounted here with 145 soldiers and a searchlight.

The battery was first built in 1637, under the Ming Chongzhen emperor, at the narrowest point of the Min River mouth. In 1657, during the Qing Shunzhi reign, batteries were added on both the Changmen and Jinpai hills. In 1884, during the Sino-French War, it hit the French cruiser La Galissonnière before being destroyed by the French fleet. In April 1941, Japanese forces removed the cannons and blew up the battery.

The French fleet called it Fort Blanc, or White Fort, during the 1884 Sino-French War. In 1881 a ceremonial platform, the Litai, was added to return salutes from foreign warships, and from 1907 to 1909 the fort ran a gunnery school that graduated 100 cadets.

The battery stands on Dianguang Hill in Changmen village, Guantou town, Lianjiang county, on the north bank of the Min River mouth opposite Jinshan on the south bank. The site is an open, unmaintained heritage area with damaged structures, so watch your footing. Bring water and sun protection; the hilltop offers no shade or services.

The battery's name in French records is Fort Blanc, "White Fort", used by the French fleet during the Sino-French War. The main rammed-earth rampart on Dianguang Hill stood 12 m high, 1.5 m thick and nearly 300 m around, enclosing 50 mu. Japanese troops in April 1941 hauled the guns away and blew up the works.
