Chilbul-am,  the Seven Buddhas Rocks and Hermitage
The main triad is Sokgamoni-bul  [Sakyamuni Buddha, 563-483 BCE]  flanked by standing
Gwanse-eum-bosal [觀世音菩薩, Avalokitesvara the Bodhisattva of Compassion] on the left and
Munsu-bosal [文殊菩薩, Manjusri the Bodhisattva of Wisdom] on the right.  There is a 4-sided
rock in front of it with a Buddha carved on each side; their identities are controversial.
Nam-san Shinseon-am,  a separate devotional site with an excellent carving of Amita-bul  [Amitabha
the Buddha of Western Paradise], sort of a "bonus" to this already-amazing place,  dramatically
perched on the cliff right above Chilbul-am, offering a wonderful view towards
Toham-san to the east.
Samseong-gak  [Three Spirits Shrine]
Samseong paintings of the Samseong-gak
excellent photos of this site from
the good
January 2013 post on
Dale's Korean Temple Adventures
Shinseon-am, it's carving of Gwanse-eum-bosal and the view down of Chilbul-am's Samseong-gak's roof from it.
