Phu Phra is a small mountain located . On one of its cliff faces, there are bas-reliefs of Buddha images from the U Thong period. They date from the late 13th – late 14th century, around the early Ayutthaya period. Each April, a three-day fair is held at the temple, Wat Sila, to pay homage to the drawings.
The bas-reliefs are currently sheltered by a roof. Amongst the depictions is a large Buddha image, looming over two meters high and 1.5 meters wide, named Phrachao-Ong Tue. Another Buddha image, a small 17-centimeter high sandstone statue, is in a similar seated posture. Seven other images are situated around a sandstone column.
