Taijiang in the 16th and 17th centuries was an inland sea bordered by the Beixianwei and Kunshen Islet sandbars.
A vital conduit between the mainland and ocean, it was home to Taiwan's earliest human settlement and culture.
The Siraya tribe lived on the shores of the Taijiang inland sea interacting with Han Chinese、Japanese Dutch and other foreigners who arrived via the ocean.
In 1624 the Dutch occupied Dayuan and built the city of Zeelandia there.
The Dutch East India Co. used Taijiang as a trading post in the Far East, thus ensuring its place in history.
