Probably the oldest thing in this temple would be the stupas for the monk Yil Yeon. At first I could not notice the stupas, because those stupas were located in the corner of the temple.
The style of the the stupa was as same as that of other stupas made in the Goryeo dynasty.
The patterns were carved on the surface of the stupa body. But it was not easy to identify what those patterns were.
Fortunately, the copy of the patterns carved on the body of the stupa was exhibited in the provisional building stood at the corner of the temple.
The patterns looked like the boddhisattvas and the animals.
