Modern Taiwan traces its origins to a single year: 1624, when the Dutch East India Company established a colonial base at Anping, on the southwestern coast of the island they called Formosa. The Dutch built Fort Zeelandia as a trading outpost on lucrative routes between Japan, China, and the Malay world. They held it for 38 years — until 1662, when Ming loyalist general Koxinga (Zheng Chenggong) besieged the fort and forced a Dutch surrender, bringing Taiwan under Chinese influence for the first time. Koxinga died just four months after his victory, but he became a folk hero of almost mythological proportions; his shrine still draws devotees in Tainan today. His grandson surrendered control to the Qing dynasty, and Tainan was made the capital of Taiwan County under Fujian Province — a status it held until 1887, when the capital shifted to Taipei. By then the city had already passed through another transformation: the Second Opium War of 1858 had forced Anping port open to foreign trade, and British merchants brought new commerce and a new cosmopolitan energy.

When Japan acquired Taiwan after the Sino-Japanese War of 1895, Tainan's civic leaders briefly tried to declare independence — possibly the first formal attempt at Taiwanese self-governance, though it lasted only days before Japanese forces arrived. Anti-Japanese sentiment found a violent outlet in the Tapani Incident of 1915, when Aboriginal and Han Chinese fighters stormed several police stations across Tainan county. The uprising was brutally crushed, and Japan responded with intensified assimilation policies: Taiwanese residents were pressured to adopt Japanese names and Shinto religious practices. Yet the Japanese period also brought modern infrastructure, urban planning, and a handful of elegant colonial buildings that still stand out against the city's otherwise modest postwar skyline. After Japan's withdrawal in 1945, the Kuomintang arrived from the mainland. Under Chiang Kai-shek's rule, Tainan residents who showed any hint of political opposition faced harsh treatment. The city has carried that memory. Southern Taiwan, including Tainan, remains the most strongly pro-independence region in the country.

With 1.85 million people (as of 2022), Tainan is Taiwan's fifth-largest city by population — but it feels nothing like its size. Very few buildings rise above five or six stories. Most are two or three. The result is a city spread horizontally across the coastal plain, its low profile broken by temple rooflines and banyan trees, with one extraordinary exception: the Anping Tree House, a former warehouse where massive banyans have grown through the walls and roof, their roots swallowing the structure over decades. The city's historical core clusters around Chihkan Tower and Zhongzheng Road, inside what were once Qing-dynasty city walls, and in Anping District. Qigu District, to the northeast, preserves salt fields from the region's long history of salt production. And Yanshui District holds an annual event unlike anything else in Asia: a fireworks festival during Lunar New Year in which participants stand inside cascading beehive rockets, thousands of them, going off simultaneously.

Tainan's nickname — the City of Snacks, or 小吃城 — is not marketing copy. It is a genuine culinary reputation built over centuries of port life, agricultural abundance, and a culture that treats eating as both pleasure and identity. The long association with Anping port means oysters appear everywhere: in oyster omelettes (蚵仔煎), in thin noodles (蚵仔麵線), cooked in ways distinct from the versions made further north. Danzai noodles (擔仔麵) originated here. So did coffin toast (棺材板) — deep-fried bread stuffed with chicken, seafood, and milk-based sauce, named for its shape. More than two dozen night markets operate throughout the city, most running only on specific days of the week. The surrounding agricultural region, one of Taiwan's most productive, supplies the fresh ingredients that likely gave rise to this whole culture. And then there is bubble tea: the Hanlin Tea House in Tainan is one of two establishments that claim to have invented it.

The temples of Tainan are not merely historical artifacts. They are active, central to daily life in a way that has largely faded in Taiwan's bigger cities. Old Taoist customs that were suppressed or forgotten elsewhere — on the mainland during the Cultural Revolution, or simply overwhelmed by modernity in Taipei — are still observed here. The city hosts more temple parades than anywhere else in Taiwan, and fighter jets from nearby air bases make low passes over the city up to thirty times a day, mixing ancient ceremony with the noise of modern defense. The Tainan dialect of Taiwanese is considered the prestige form of the language, spoken by many residents and cherished as an expression of a cultural identity that has survived every occupier. In a city this old, in a country where identity has been contested across centuries, the persistence of that language, those temples, and those snack vendors is its own kind of victory.
