Hwanbyeokdang Pavilion was built by Yeongcheonja Sinjam and was also called Byeokgandang, which is recorded in Go Gyeong-myeong's Yuseoseongnok. The building has a hipped-and-gabled roof with three bays in the front space and two bays in the inside space. It is a modified form in which the two rooms in the middle are used as rooms, and the front and right sides are floors. Originally, it was a traditional pavilion, but it seems to have changed to its current form as it was expanded later. A tablet written by Uam Song Si-yeol hangs here, and the poems of Seokcheon Im Eok-ryeong and Jo Ja-i are on a signboard. There are two poems written by Jeong Cheol about Hwanbyeokdang Pavilion, which are published in Songgangsokjip and Gwangjumokji. Jeong Cheol's 4th-generation descendant Jeong Su-hwan bought it from Kim Yun-je's descendants, and Yeon Il-jeong's family is currently managing it.
