Buddhist stone art in the Cheongyang region remains in relatively diverse types, including stone pedestals, stone pagodas, stone Buddhas, and stone lanterns. It is presumed that the stone pedestal at Janggoksa Temple was created in the late Silla Dynasty, the earliest period, and most other stone art was created during the Goryeo Dynasty.
 The art historical significance of Buddhist stone art in the Cheongyang region was examined in two major ways. First, the traditional style of Unified Silla is strongly reflected. The stone pedestal of Janggoksa Temple inherits the style of the square three-tiered Buddha statue pedestal of Silla, while showing new changes and inventions. In particular, it is significant in the history of Korean Buddhist art in that it is the only type of Buddhist pedestal that has a roof structure with pillars. The stone standing Buddha triad in Eupnae-ri, Cheongyang, also attracts attention as it strongly reflects the traditional style of the Unified Silla. The Chungcheongnam-do region is a place where temples were built by the royal family from the early days of the founding of the Goryeo Dynasty and stone art with a unique aesthetic of Goryeo, known as the Goryeo New Style, was created. This is significant in that it is almost the only one in the Chungcheongnam-do region, where Goryeo Silla Buddha statues were prevalent, that strongly follows the traditional style of Unified Silla.
 Next, due to the geographical characteristic of Cheongyang being located in the center of Chungcheongnam-do, the influence relationship between the surrounding area and the stone pagoda style was identified. Lastly, it was confirmed that Chilgapsan Mountain is the center of Buddhist art in the Cheongyang region, as temples and Buddhist art, such as Janggoksa Temple, Dorimsaji Temple, and Jeonghyesa Temple, are concentrated in Chilgapsan Mountain.
