Wat Phra Sing      Wat Phra Sing was built in the 14th century by King Phayco of the Mengrai dynasty. It may have been the first monastery to house the Emerald Buddha, a cultural treasure that now resides at the royal palace in Bangkok. Wat Phra Sing currently houses Pra Thongtip, the most venerated Buddha statue in northern Thailand. Cast in 1477, it is made of an alloy of gold and copper.
