The Ping River courses through the Kamphaeng Phet Historical Park, a UNESCO-recognized World Heritage Site which is comprised of a diverse array of ancient monuments. A common aesthetic runs through the various ruins, which include temples, pagodas and fallen towns, resulting in a beautiful blend of contemporary Sukhothai and Ayutthaya styles. Also noteworthy is the variety of materials used at each site: the eastern bank is home to larger architecture built with laterite in contrast to the smaller, brick-made monuments in the west bank’s Nakhon Chum town.
