土壟灣堰, Historical water dam in Tainan, Taiwan
The Toulongwan Dam is an earthen water barrier that stretches across the landscape to manage water flow for the agricultural fields surrounding it. Its simple construction from compacted earth demonstrates how water control has been maintained in this region over time.
The structure was built in the early 1900s to secure water for farming in this region. It has since remained a key part of southern Taiwan's water management system and has been adapted to meet local needs over the decades.
The dam reflects how local farmers have managed water for generations, and you can see the channels that direct water to rice fields throughout the surrounding landscape.
Visitors can best explore the dam during the dry season when the paths around it are easily walkable. It is helpful to ask locals about access routes and current conditions before visiting to make the most of your time there.
The dam was built entirely from rammed earth without modern cement, preserving its original hand-crafted technique. This makes it a rare example of traditional construction methods that still function effectively today.
