Tung Chung Battery, Artillery battery in Islands District, Hong Kong.

Tung Chung Battery is a former coastal artillery battery on Lantau Island, Hong Kong, built in 1817. It originally had two cannon emplacements, seven guard houses and a powder magazine, but today only an L-shaped granite wall with a corner gun platform remains. It was declared a monument on 11 November 1983.

The battery was built in 1817 to defend the bay against pirates who were active along this stretch of coast. After decades buried under thick vegetation, it was rediscovered in 1980 and declared a monument in 1983.

The name follows the district and bay it guarded, and the site is recorded in the Guangdong Annals as one of two forts built at the base of "Rocky Lion Hill" (Shek She, 石獅山). The battery's granite was later quarried away by a monk, who reused the stone to rebuild the collapsed Ma Wan Chung bridge, renaming it Mi Le Bridge (彌勒橋).

The site is free to enter and sits in a quieter part of Lantau Island, reachable by public transport. The path leading to it can be uneven and steep in places, so solid footwear is a good idea before heading out.

From the spot where the cannons once pointed toward pirate ships, visitors today look out directly over Hong Kong International Airport. That view, from a stone gun emplacement to one of the world's busiest airports, captures two centuries of change in a single glance.
