Gangziliao Fort

　　Classified as a third-grade historical site, Gangziliao Fort is situated in the Gangziliao mountain area to the northeast of Keelung City. Together with other forts such as Ershawan, Shihciuling, and Bai Mi Wan, it forms a strategic network that once protected Keelung Harbor. The fort has withstood historical battles including the Sino-French War and the Japanese invasion during the Bèiwèi period, making it an over century-old historic battleground.

　　The fort covers a large area and is divided into three sections. The first section is relatively small, featuring the remains of three buildings and two bunkers. Only broken brick walls of the buildings remain, likely general barracks, while the bunkers were constructed from stacked stones and topped with arched concrete, which helped preserve them intact.

　　The second section is enclosed by a fan-shaped stone wall. On either side are the foundations of two buildings, and beneath a hill at the back lies a large bunker that served as the command post. The bunker is entirely built from stone, with walls and a roof both 1.5 meters thick, making it the most solid structure in the fort aside from the gun emplacements. Opposite the bunker are two connected tunnels, which open up to a wide view—offering a panoramic sight of the Badaozhi area. However, the tunnels are dark, damp, and slippery, and their exits are situated on steep cliffs, so entry is not recommended without caution.

　　Behind the bunker, stone steps and a path lead to the top of Gangziliao Mountain, where the entire Badaozhi Fishing Port, Wangyou Valley, Hoping Island, Keelung Islet, and Bitou Cape come into view. Walking along the ridge, small artillery positions hidden among overgrown vegetation appear one after another. These four aligned gun emplacements offer excellent vantage points, making it easy to see why they were built here.

　　Descending via the stairs between the smaller gun emplacements, you will reach the grand third section. This area features a canyon-like passage similar in function to that of Dawulun Fort, connecting six massive gun emplacements. These emplacements are arranged in three pairs built into recesses in the mountainside, surrounded by stone walls up to 10 feet high—forming defenses stronger than any other historic forts in Keelung. Each circular gun position is about 5 meters in diameter. Although the types of cannons originally used are no longer known, they were likely no less formidable than the Armstrong guns at Haimen Tianxian.

　　Transportation Guide: Take Keelung City Bus No. 104 or 205 from in front of Keelung Railway Station, get off at Erxin Middle School Station, then walk up Lide Road. After about 1.2 km, turn left at the sign for Charity Temple, and continue straight for about 1 km to reach the fort.
