One is through Cheongungyo and Baegungyo Bridge in the east leading to the Daeungjeon Hall, and the other is through Yeonhwagyo and Chilbogyo Bridge in the west that is connected to Anyangmun Gate leading to Geungnakjeon Hall (the temple of abode land).
This bridge was not for earthly people, but only for those who had realized the western abode world.The bridge is made of 18 steps among which 10 steps at the lower part are Yeonhwagyo Bridge and 8 steps at the upper part are Chilbogyo Bridge.
This bridge is smaller than Cheongungyo and Baegungyo Bridge , but the structure and the formation are very similar to it.
The similar points are the unique formation of bridge-shape staircase, the 45 slopes, and the rainbow-shaped arch under the bridges.
But in spite of the similarity in formation, it has its own unique characteristic.
It is the prominent carvings of lotus flower petals on each steps of Yeonhwagyo Bridge.
However, these designs are dimly left now because of the tramping of a lot of people for a long time.
So the bridge is now blocked from people.
They say that this bridge was climbed at the time of its building by a lot of people who wished to die an easy and peaceful death, and that Queen of King Heongang became a Buddhist monk to wish her husband King die an easy and peaceful death.This bridge seems to have been built in the 10th year of King Gyeongdeok in the Unified Silla Dynasty at the same time with Cheongungyo and Baegungyo Bridge.
The bridge shows delicate beauty, while the eastern Cheongungyo and Baegungyo Bridges shows grand beauty.
So they give the Bulguksa Temple some harmony and variation in formative beauty.
