The central Buddha is 2.8 meters tall, while the flanking Bodhisattvas measure approximately 1.7 meters each.
The sculptures were rediscovered by a local resident by chance while searching for a lost goat.
The Maitreya Bodhisattva is depicted in a 'thinking' posture with one leg crossed over the other, a common motif in East Asian Buddhist art.
The protective structure currently enclosing the statues is a modern replacement designed to prevent weather-related erosion of the soft granite.
The site was historically part of a major trade route used to exchange goods and culture with China.
Art historians often contrast the 'Smile of Baekje' here with the more formal, rigid expressions found in contemporary Silla statues.
The Seosan Rock-carved Triad Buddha, often referred to as the 'Smile of Baekje,' is a 7th-century rock relief located on a cliff face in Unsan-myeon. The sculpture features a central Sakyamuni Buddha flanked by a standing Bodhisattva and a seated Maitreya Bodhisattva. It was carved during the late Baekje period when the site served as a vital transit point on the route connecting the Baekje capital to the Yellow Sea. The triad's distinctive facial expressions shift in visibility depending on the angle and intensity of sunlight striking the rock surface. It is designated as National Treasure No. 84 of South Korea. The carvings were discovered by a local villager as recently as 1959. The figures are carved directly into a granite cliff sheltered by a protective wooden pavilion. The site represents the culmination of Buddhist art from the Baekje kingdom before its fall to the Silla-Tang alliance.

Bring a polarizing filter for your camera to manage the high contrast between the shadowed rock face and direct sunlight.
Walk the short trail loop leading up to the site to see the natural rock formations that precede the cliff.
Visit during different times of the day if possible, as the changing light alters the appearance of the 'smile' on the faces.
Do not attempt to climb the rock face or lean over the protective railings for closer inspection.
The site is open year-round, though access may be restricted during extreme weather events or forest fire prevention periods.
Maintain a quiet tone as the site is considered a sacred cultural space; do not touch the ancient stone carvings.
