The Convention of Peking ended the Second Opium War and compelled China to open additional ports to Western commerce. Takau — the harbor that would become Kaohsiung — was among those designated treaty ports. Foreign merchants arrived quickly, and with them came the practical problem of navigating an unfamiliar coastline. The harbor entrance, flanked on the west by Cijin Island's barrier strip, required precise piloting. British engineers supplied the solution: a Chinese-style rectangular lighthouse built from local red brick, positioned at the summit of Mount Ki-au (旗後山) to command the widest possible view of incoming traffic. It was a pragmatic structure built to serve foreign commercial interests, but it became a permanent fixture in the harbor's geography.

When Japan acquired Taiwan after the Treaty of Shimonoseki in 1895, the colonial administration set about modernizing the island's infrastructure according to Japanese and Western standards. The harbor at Kaohsiung — renamed and expanded — became a priority. As part of a broader harbor expansion project, the original lighthouse was demolished and rebuilt in 1916. Two years later, in 1918, it underwent renovation that produced the structure visitors see today: a cylindrical white tower sitting on a base detailed in Baroque style, a hybrid of Western architectural ornament and East Asian setting that characterizes much of Taiwan's Japanese-era building stock. The mix feels natural now, embedded as it is in the hillside above a harbor that has always been a crossroads.

The lighthouse sits at the top of Mount Ki-au, and the climb repays the effort. From the tower, the entire Port of Kaohsiung opens up below: the long parallel lines of container berths, the bulk carriers anchored in the outer roads, the narrow strait between Cijin Island and the city proper through which all this traffic must pass. On a clear day the view extends across the harbor mouth to the open Taiwan Strait, and south to where the coastline curves toward Siaogang. Adjacent to the lighthouse, one of the historic buildings has been converted to a café — a sensible amenity for the climb, and a reminder that heritage sites can absorb new uses without losing their character. The lighthouse was designated a Historical Building in 1985, which opened it to public visits.

The lighthouse's location on Cijin Island shapes everything about the experience of visiting it. Cijin is a narrow strip of land — barely a few hundred meters wide in places — separating Kaohsiung Harbor from the Taiwan Strait. To reach it from the city center, visitors take a short ferry crossing, a transition that feels more significant than the distance warrants: suddenly the scale changes, the pace slows, and the harbor views open up on both sides. The island has temples, a historic fort, seafood restaurants, and beachfront promenades, making the lighthouse one stop on a natural circuit. From the hilltop, looking east across the harbor at Kaohsiung's skyline, the city that grew up around this trade route is visible in its entirety — a panorama that the first British engineers, building their modest beacon in 1883, could not have imagined.
