What I saw in front of Dae Wung Jeon in Ssang Gye Sa temple was the pagod which seemed to be made in the Goryeo dynasty. As estimating the period of being built, it seemed to be strong connection with the Mongolian Invasion. Mongolians created the Yuan Won dynasty in China. And the Buddhism in the Yuan dynasty seemed to be deeply influenced by the Buddhism in Tibet.
The pagoda was very high and it was not easy to take the photo of it in one shot without the distortion of the image.
There were other pagodas in other temples which were similar to this pagoda.
Besides the Dae Wung Jeon, there was the carved Buddha relief on the rock.
In general, it seemed to be made in late Goryeo dynasty.
The carving skill was not deliberate. It seemed that ordinary people carved this relief.
In Goryeo dynasty, local people began to made their statues by themselves without the support of the central government.
