Pha Sam Ngao is an important historic site and a spiritual landmark deeply connected to the identity of Sam Ngao District. It plays a significant role in northern Thai history and local beliefs surrounding the founding of early cities.

Legend of Queen Chamadevi According to historical chronicles, around 657 CE (circa 1200 BE), Queen Chamadevi traveled by river from Lavo (present-day Lopburi) to rule Hariphunchai (modern Lamphun). When her royal procession reached this area, an auspicious vision appeared in the form of Buddha shadows on the cliff face. She therefore ordered artisans to carve three Buddha images into the cliff, giving rise to the name “Sam Ngao,” meaning “Three Shadows.”

Artistic Characteristics Three deep niches were carved into the rock face, each housing a gilded wooden standing Buddha image. These images remain in their original positions and once served as visible sacred landmarks for travelers navigating the Ping River, who could pay their respects from afar.

Surrounding Atmosphere Today, the area has been landscaped into a peaceful riverside site with shaded seating and scenic viewpoints. The calm environment makes Pha Sam Ngao ideal for quiet reflection, historical exploration, and enjoying the natural beauty of the sacred cliff beside the flowing river.
