Cape Collinson Battery, Artillery battery in Eastern District, Hong Kong

Cape Collinson Battery is a 1938 coastal battery on Hong Kong Island's eastern shore. Its two 6-inch guns stood on Pottinger Peak, where an observation post watched ships entering Victoria Harbour through Lei Yue Mun. On the shore below, concrete shelters protected searchlights, and a bunker housed the generator that powered them.

The fortification was built in the late colonial period as part of Hong Kong's defense system to protect ships and trade routes from attacks. It was constructed during a time when Britain was strengthening military control over the region and its waters.

The fortification reflects British colonial military methods and engineering approaches that shaped Hong Kong's development during that era. Walking through the site reveals how defensive thinking influenced the layout and construction of the coastal settlement.

The site is accessible via marked hiking trails that depart from Chai Wan MTR station and head eastward along Cape Collinson Road toward the coast. Proper footwear and plenty of water are recommended for exploring the grounds and viewing the gun emplacements.

The generator bunker's curved front wall was built to shield its ventilation openings from shell splinters. Of the two concrete searchlight shelters on the shore below, one has collapsed and the other's roof is partly down; the site is now a popular photo stop, and visitors climbing or hanging from the shelters speed their decay.
