The use of broken ceramic tiles (potsherds) prevents salt crystals from mixing with mud, resulting in a cleaner, higher-grade product.
The fields cover an area of approximately 2,000 square meters, partitioned into individual evaporation plots.
The salt produced here was historically known as 'fist salt' due to the shape of the salt crystals collected by workers' hands.
The ground pattern is specifically designed to maximize solar absorption to accelerate the water evaporation process.
The salt here has a distinct trace mineral profile compared to modern mechanically produced salt.
Jingzaijiao Tile-paved Salt Fields is the oldest remaining salt field in Tainan, established in 1818 during the Qing Dynasty. The site features a mosaic-like pattern of ceramic shards embedded in the ground to harvest salt via solar evaporation. It served as the primary salt production area for the Beimen region for nearly two centuries. The fields are divided into a grid of low-lying, interconnected rectangular ponds. Salt workers maintain the area to preserve historical harvesting techniques. The site was rehabilitated in 2002 to prevent the local salt industry from fading into obscurity. Visitors can observe the crystallizing process of sea water directly on the tiled surfaces. It currently functions as an open-air cultural site highlighting Tainan's coastal heritage.

Wear footwear that is comfortable for walking on uneven, dirt-path surfaces near the ponds.
Bring sun protection such as a hat or umbrella, as there is very little natural shade in the open field area.
Check local tide and weather forecasts, as heavy rain can temporarily halt the salt crystallization process.
Avoid visiting during mid-day in summer, as the lack of shade and high heat index can be physically taxing.
Operations are sometimes suspended during typhoon warnings or periods of extreme, prolonged rainfall.
Do not touch the salt or step into the evaporation ponds, as they are part of a delicate production cycle.
