Sonjuk Bridge is a historic stone bridge situated in the city of Kaesong, North Korea. This small bridge, made of Korean greenish blue stone, was constructed in 1290 during the Goryeo Dynasty and is a renowned Cultural Heritage site. It spans just 7.35 meters in length and 3.36 meters in width and is supported by simple yet elegant stone piers. Sonjuk Bridge is notable for its association with the renowned scholar-official Jeong Mong-ju, who was loyal to the Goryeo regime. His assassination in 1392, on what many believe to have been Sonjuk Bridge, symbolized the end of the Goryeo Dynasty and the beginning of the Joseon Dynasty. Today, the bridge is considered a symbol of loyalty and is a popular destination for visitors interested in Korean history and culture. However, no longer used as a bridge, it stands as a monument and educational site with inscriptions describing its historical significance, providing a tangible connection to the storied past of the region.
