Tai Po as a populated place, could be traced back to the
Stone Age. An archaeological site in
Yuen Chau Tsai, had discovered stone axe and pottery which was believed to be made in
Neolithic era. The indigenous inhabitants of Tai Po lived by clamming and pearl farming in Tai Po Hoi (literally
Tai Po Sea;
Tolo Harbour) since at least AD 963.
Tang clan migrated from the area north of the border of modern-day Hong Kong to the modern-day
New Territories of Hong Kong in the
Song dynasty of China. A branch of the Tang clan was split from
Lung Yeuk Tau of the modern-day New Territories, to establish the village in Tai Po Tau. The Tai Po Tau branch and Lung Yeuk Tau branch also founded the first Tai Po Hui market town (also known as Tai Po Tau Hui), despite it is now defunct and the area now known as Tai Po Old Market. The area around the first market town also lived other people that were not from the Tang clan. They formed an inter-villages alliance
Tai Po Tsat Yeuk (literally
Tai Po Seven Alliances; each alliance contained one or more villages). The inter-villages alliance founded another market town
Tai Wo Shi (literally
Tai Wo market) after the
Qing government ruled that Tai Po Hui (Tai Po Tau Hui) belonged to Tangs, other clans cannot open shops in Tang's market town. However, Tai Wo Shi replaced the original Tai Po Hui (Tai Po Tau Hui) as the main market and took the name Tai Po Hui (anglicized as Tai Po Market). The old market town thus became Tai Po Kau Hui (anglicized as Tai Po Old Market; ). During the British colonial rule, a
District Office, a
police station, two railway stations:
Tai Po Market railway station and
Tai Po Kau railway station (in
Tai Po Kau; ) and other public facilities were built within the modern-day area that belongs to the new town and the administrative district. Most of them were in close distance to the market town of Tai Po at that time. In the 1970s, the Hong Kong government began to develop satellite towns:
Tai Po Industrial Estate, the first industrial estate in Hong Kong was built in the reclaimed land of the former Tai Po Hoi in 1974; Tai Po was named as a site to build "
new town" in 1979, which the government obtains lands by reclamation of the river mouth and Tai Po Hoi. The new town was also designed to incorporate and interact with the existing market town. The first
public housing estate of
Tai Po New Town: Tai Yuen Estate – was established in 1981. The population has soared to 320,000, and Tai Po New Town began to prosper following the completion of the
Tolo Highway which was integrated with the older urban areas. At present, due to the development of the new town, the place name Tai Po may refer to Tai Po New Town or the historical area centre Tai Po Market, or the Tai Po District (excluding exclave Sai Kung North) that covers the new town and
Lam Tsuen Valley and another area. However, the boundary of Tai Po was not defined. In contrast, the namesake
election constituency of Tai Po Market had its legally defined boundary, as well as Tai Po District; Tai Po New Town also had its officially defined boundary in urban planning regulation and law. Moreover, Hong Kong police, as well as primary and secondary schools district, had their own boundaries. In February 2023, model and influencer
Abby Choi Tin-Fung was found murdered in a village house in
Lung Mei. In November 2025, a
level 5 fire started in Wang Fuk Court, Tai Po, leaving at least people dead. ==Education==
