Cihou Fort & Xiongzhen North Gate

Cihou Fort (旗後砲臺, also written 旗后砲台) and Xiongzhen North Gate (雄鎮北門) are a pair of late Qing-dynasty coastal defense fortifications that guarded the northern and southern approaches to the entrance of Takao Harbor (modern Kaohsiung Harbor) in southern Taiwan.

HISTORICAL BACKGROUND — THE MUDAN INCIDENT AND COASTAL DEFENSE REFORM

In 1874 (Tongzhi 13th year), a Japanese punitive expedition attacked indigenous Paiwan communities near Hengchun in southern Taiwan — the so-called Mudan Incident (牡丹社事件). The crisis exposed the vulnerability of Taiwan's defenses and prompted the Qing court to dispatch Shen Baozhen (沈葆楨), the Imperial Commissioner and Minister of Naval Affairs, to Taiwan to overhaul coastal fortifications. Shen ordered the construction of modern Western-style gun batteries at three strategic elevations around Takao Harbor: Qihou Mountain (旗後山, high/medium position), Shaochuantou (哨船頭, low position), and Chaishan/Shoushan (柴山, high position). This three-tier defense system was designed to cover the harbor entrance with overlapping fields of fire at different angles and elevations.

CONSTRUCTION (1875–1876)

Construction of both fortifications began in 1875 (Guangxu 1st year) under the supervision of Huai Army commander Tang Dingkui (唐定奎) and deputy general Wang Fulu (王福祿). The Qing authorities engaged a British military engineer, J.W. Harwood (哈務德), to design and oversee the construction according to modern Western military engineering principles.

Cihou Fort was built atop Qihou Mountain on the northern tip of Qijin Peninsula (旗津半島), commanding the harbor entrance from an elevated position with sea views on three sides. The fort follows a rectangular plan divided into three functional zones: a parade ground and barracks to the north, a command headquarters in the center, and an ammunition magazine and battery positions to the south. Four British-made Armstrong guns — recorded for 1894 as 8-inch breech-loaders — were mounted on open emplacements facing the harbor channel. The architecture uniquely blends Chinese and Western styles — the red brick walls incorporate traditional Chinese decorative motifs including paired "囍" (double happiness) characters and bat reliefs symbolizing good fortune, while the structural engineering follows Western fortress design. The main gate bears the inscription "威震天南" (Awe-Inspiring Power of the Southern Skies), expressing the fort's mission to dominate the southern approaches.

Xiongzhen North Gate (雄鎮北門, "Mighty Fortress Guarding the North Gate") was built simultaneously at the Shaochuantou promontory on the opposite (northern) side of the harbor entrance, at a lower elevation to provide close-range crossfire coverage. The gate structure features a thick stone archway with the characters "雄鎮北門" inscribed above, and the surrounding battery was armed with cannons covering the harbor channel. Together with Cihou Fort's elevated position, the two installations created a complementary defense network — high-angle plunging fire from Cihou combined with direct-fire coverage from Xiongzhen.

THE 1895 BATTLE OF TAKAO

During the First Sino-Japanese War, the Treaty of Shimonoseki (1895) ceded Taiwan to Japan. When local resistance forces refused to accept Japanese rule, on October 15, 1895, Japanese warships of the Standing Fleet under Vice Admiral Arichi Shinanojō, led by the cruiser Yoshino (吉野) with Akitsushima, bombarded Cihou Fort. With the commanding officer absent and only a skeleton garrison remaining, the fort managed to fire only five cannon rounds before falling silent. The Japanese bombardment damaged the fort's gate, destroying the first two characters "威震" of the inscription "威震天南." Japanese forces quickly occupied both fortifications, marking the beginning of 50 years of colonial rule in southern Taiwan.

JAPANESE COLONIAL PERIOD AND WORLD WAR II

Under Japanese rule (1895–1945), Cihou Fort's original military function was largely abandoned and the fortification fell into disuse. The Armstrong cannons were removed. However, during the Pacific War, the strategic importance of Kaohsiung Harbor — which had become a major Imperial Japanese Navy logistics base and shipyard — brought renewed attention to harbor defenses. The Japanese military converted Cihou Fort into an anti-aircraft gun (高射砲) emplacement, clearing the old cannon positions and installing modern anti-aircraft weapons to defend against Allied air raids. Several reinforced concrete bunkers and machine-gun nests were added around the fort and between the fort and the adjacent Kaohsiung Lighthouse (高雄燈塔). These WWII-era additions are still visible today.

Kaohsiung Harbor itself was heavily bombed by Allied forces during 1944–1945, with the port facilities, shipyards, and oil storage installations suffering extensive damage. The fort's anti-aircraft batteries were part of the harbor's air defense network during these attacks.

POST-WAR AND HERITAGE DESIGNATION

After Japan's surrender in 1945, the Republic of China military took over the fortifications and added further bunker positions. The fort gradually deteriorated over the following decades. In 1985, Taiwan's Ministry of the Interior designated Cihou Fort a Second-Class Historic Site and Xiongzhen North Gate a Third-Class Historic Site; Cihou Fort was upgraded to a national monument (國定古蹟) in 2019, while Xiongzhen North Gate is now a Kaohsiung municipal monument. The Kaohsiung City Government began a comprehensive restoration of Cihou Fort in 1991, completed in 1995, after which it was opened to the public. Today both sites are popular heritage tourism destinations, with Cihou Fort offering panoramic views of Kaohsiung Harbor, the Qijin coastline, and the city skyline.
