The original construction of the reservoir is recorded in the Samguk Sagi, the oldest surviving history of Korea.
The reservoir was estimated to have a circumference of approximately 18 kilometers at its peak use.
It served as the primary irrigation source for the vast Gimje plains, known historically as the 'granary of Korea'.
The twin dragon sculptures are based on the legend of the maiden Dan-yeo, who was said to be sacrificed to appease the dragon of the reservoir.
Modern archaeologists have identified five distinct sluice gate sites along the preserved dike sections.
Byeokgoljae is Korea's oldest and largest man-made irrigation reservoir, originally constructed in 330 AD during the Baekje Kingdom. The site preserves remnants of ancient dikes spanning several kilometers, showcasing early Korean hydraulic engineering. The modern complex includes the Gimje Arirang Literature Museum and the Byeokgoljae Agricultural Culture Museum. Two large wooden dragon sculptures serve as iconic markers of the site's historical significance in regional agriculture. Excavations have revealed historical sluice gates that reflect advanced water management techniques from the Three Kingdoms period. The surrounding area functions as an expansive educational park dedicated to the history of rice farming in the Honam plains. It remains a key landmark for understanding the structural foundations of traditional Korean agrarian society.
