Origin of Jebeewon
Origin of Yeonmisa

"Yeonbiwon-bulsa is located in the southern part of Mt. Ohdo about 5km away from the village to the northwest.
A big rock was erected, on which an image of Buddha was carved, and it is about 30m high. It was constructed in the 8th year of Jungkwan in Dang Dynasty, and it has a 6-story roof.
The shape of the building is like wings spread in the sky. Afterwards, it was reconstructed twice, but old materials were used for the columns and beams, etc."

According to the record above, the construction of the stone Buddhist image and the castle seems to have been carried out in the year of 634 AD(the third year of Sunduk Queen in the Shila Dynasty). Besides, it was found out that even until 1608 when the book, Yeong-gaji, was published, they were preserved as it was.
However, the name of the castle was gone, only to leave Yeonmiwon-bulsa recorded, which shows that the original name of the temple was already lost. The following is another record saying:

"Priest Boduk had 11 prestigious pupils, among whom Musanghwasang had Gumdongsa built with his pupil Gimchui and others, both Priest Jukmyul and Priest Eiyoong had Jingoosa built, Jisu had Daeseungsa built, Sujeong Yoomasa built, Sadae had Jungdaesa built with Gyeyook and others, Gaewonhwasang had Gaewonsa built and Myoungduk had Yeongoosa built."

'Yeongoosa' shown in this record indicates the very 'Yeonmisa', which is not quite sure without a detailed record capable to support this assumption, but it is quite desirable to base the assumption on the legends handed down orally by the priests in Yeonmisa and the holes and foundation stones seemingly used to build the castle roof above the Jebeewon Mireuk Buddhist image.

In other words, the swallow-shaped and many-storied building covers the stone Buddhist statue and even the rock in front of it, which indicates that the way of constructing the temple is similar to that of a stone cavern temple, and this space was the Buddhist sanctum, whose location corresponded to the beak of a swallow. That's why the temple has been called Yeongoosa.
