Wat Phra Singh houses an important Buddha statue: the Phra Buddha Sihing which gives the temple its name. The origins of this statue are unknown but, according to legend, it was based on the lion of Shakya, a statue since lost which used to be housed in the Mahabodhi Temple of Bodh Gaya (India). The Phra Buddha Sihing statue is supposed to have been brought, via Ceylon (present day Sri Lanka), to Ligor (present day Nakhon Si Thammarat and from there, via Ayutthaya, to Chiang Mai. There are two more Buddha statues in Thailand which are claimed to be the Phra Buddha Sihing: one is housed in Wat Phra Mahathat in the city of Nakhon Si Thammarat and another in the Bangkok National Museum.
It is alleged that the head of the statue had been stolen in 1922. The possibility remains that the present statue (or maybe only the head) is a copy.
Every year, during the Songkran festival, the statue is taken from Wihan Lai Kham and carried through the streets of Chiang Mai in a religious procession during which the spectators honour the statue by sprinkling water over it.
Wat Phra Singh有一所和尚大学，所以在这里经常可以看到来自柬埔寨、老挝和泰国各地的年轻和尚。他们还维护了一个和尚聊天区，用英语跟游客聊天，聊什么内容都可以，不限于佛法。
