Chan Sen Ancient City and Chan Sen Museum
(พิพิธภัณฑ์เมืองโบราณจันเสน นครสวรรค์)
Nakhon Sawan
Although Chansen City is submerged and is now a waterlogged valley, traces of its substantial 20-meter wide moat can still be seen and its many artifacts enjoyed at the nearby museum. Discoveries include earthenware such as amulets, dolls and lamps; stone items such as Buddhist wheels and forged metal earrings, spearheads and bronze Buddha images. The ancient city, founded during the Dvaravatii period, is called KhokChansen by locals.
