Nakhon Sawan
Nakhon Sawan stands near the confluence of the Ping and Nan rivers, where their waters become the Chao Phraya. The crossing, known as Pak Nam Pho, joins routes from the northern valleys to the great river flowing south through the central plain. East of the town lies the broad wetland of Bueng Boraphet. Known in earlier times as Phra Bang, the settlement occupied an important position on the southern approaches to the Sukhothai kingdom and on the waterway towards Ayutthaya.
