The town grew up around a temple. Long before Magong had walls or a city hall or a Japanese naval base, there was a shrine to Mazu — the deified form of a medieval woman from Fujian Province who became the patron goddess of sailors across the South China Sea. That temple, believed to be among the oldest dedicated to Mazu in all of Taiwan, gave the settlement its name: Makeng, in the old romanization, derived from the goddess's harbor. The city has changed its name three times since then. The temple still stands.
Magong is the county seat of Penghu — the administrative center for an archipelago of some 90 islands and islets scattered across the Taiwan Strait between Taiwan's main island and mainland China. It sits on Penghu's largest island, at the edge of a natural harbor that made it strategically valuable to every power that cycled through the region.
The name has shifted with each change of administration. The original Makeng became Makō under Japanese colonial rule in 1920, when the settlement was reorganized as a subprefecture of Hōko Prefecture and designated the center of the Mako Guard District — a regional naval command. After Taiwan's transfer to the Republic of China in 1945, Wade-Giles romanization rendered it Makung. Taiwan's adoption of Tongyong Pinyin in 2002 and then Hanyu Pinyin in 2009 produced the current spelling: Magong. Four names for one place; each a timestamp of a different era of governance.
The city proper began to take shape around 1887, during the Qing Dynasty's late administration of Taiwan, when a defensive wall was constructed and the settlement around the harbor consolidated. That was also the period when Penghu's vulnerability to outside powers was most sharply felt — French forces had occupied the islands in 1885, and the Qing response included both the city wall and intensified fortification.
Japanese control, which began in 1895 following the Treaty of Shimonoseki, transformed Magong into a major Imperial Japanese Navy base. The city served as an embarkation point for the invasion of the Philippines in 1941. American air power targeted the island repeatedly during the Second World War. After the war, Magong settled into its current identity as the civilian and administrative capital of a county that Taiwan's central government values for its strategic position in the strait.
On 25 December 1981, the settlement was formally upgraded from an urban township to a county-administered city.
Penghu's geography shapes Magong's weather in ways that residents feel every season. The archipelago sits exposed in the Taiwan Strait, where the Asian landmass and the Pacific Ocean meet in a perpetual contest of air masses. Summer brings monsoon rainfall and heat that rarely exceeds the low 30s Celsius in the afternoons, but keeps nights above 25°C for months at a stretch. Winter is not cold by temperate standards — lows rarely drop below 15°C — but the prevailing northeast winds that blow across open water make the season feel harsher than the thermometer suggests.
Magong is notably drier than the Taiwan main island — the islands sit in the rain shadow of conditions that dump precipitation on the mountains to the east. This gives Penghu a particular quality of light in dry months: clear skies over flat island terrain, the sea reflecting sunlight in every direction.
Magong pulls visitors in multiple directions. The harbor district, with its Central Street running through the old town, offers a dense concentration of temples, traditional architecture, and food stalls where local seafood dominates the menus. The Mazu Temple, the Beiji Temple, the Old City Wall, and the Chenghuang Temple cluster within walking distance of each other, making the city center an unusually intact repository of religious and historical architecture for a city of its size.
Further out, the island's geography opens up — Fenggui Cave on the southern coast, the basalt formations that define Penghu's geological identity, and the fishing ports that still drive the local economy. The city connects to the wider archipelago by road and ferry. Penghu Airport (RCQC) serves domestic flights from Kaohsiung, Tainan, Chiayi, and Taipei, making Magong the gateway through which most visitors arrive. The harbor supplements that link with ferry connections to the main island ports.
Magong sits at approximately 23.567°N, 119.583°E on Penghu's main island. Magong Airport (RCQC) lies northeast of the city center, roughly 2 nautical miles from the harbor. On approach from Kaohsiung to the southeast, the flat, low-lying Penghu archipelago appears ahead with the city visible on the western coastline of the main island. Recommended viewing altitude 2,000–4,000 ft for the full island-city-harbor relationship. The Penghu Great Bridge connecting to Siyu Island is visible to the north at this altitude. Use caution in summer months; typhoon season brings rapidly changing conditions over the open-water approaches to RCQC.
