In the middle of the Ongnyucheon Stream, there is a pavilion called Soyojeong Pavilion. The pavilion nestled like a hidden treasure in the deepest part of the Secret Garden. It was originally called “Tanseojeong Pavilion” which has the meaning of “a place to lament the time passed by”. It was later changed to the current name, which carries the meaning of “walking slowly without restrictions”. It may sound easy for normal people, but this may be a wish for a king in the Joseon Dynasty.

In 1636, during the 14th reign of King Injo, a U-shaped groove was carved on a large flat rock known as Soyoam Rock and filled with water. From the Soyojeong Pavilion, visitors can take in the entire scene of Soyoam Rock, which features a miniature waterwall and Okryucheon Stream. Sometimes the king and his subjects set their wine cups afloat on the water when they wrote poetry. The inscription “Ongnyucheon Stream” written on Soyoam Rock is said to have been written by King Injo.

The poem composed by King Sukjong was engraved on Soyoam Rock. King Jeongjo also wrote a poem about the breathtaking scenery while looking at the waterfall with his officials. In the poem “Sangrim Ten Scenes”, it describes the top ten beautiful scenes in Changdeokgung Palace; the view of Soyojeong Pavilion was ranked fifth.
