A Five-Year-Old Prince's Tomb, and Three Roads Meeting

Hyochangwon was a tomb built for a son of King Jeongjo who died at age five, and Samgakji takes its name from the three-way intersection where roads from the Han River, Seoul Station, and Itaewon once converged.

Key takeaways

Crown Prince Munhyo was the first son of King Jeongjo and his consort Uibin Seong, born in 1782 and dead by age five, in 1786. Fact (For context: King Jeongjo, who reigned 1776–1800, is remembered as one of Joseon's most significant reform-era kings.) His tomb was elevated to the formal status of Hyochangwon in 1870. Fact His birth mother, Uibin Seong, who died a few months after her son, was buried at the same site. Fact

"Samgakji" (meaning roughly "triangle point") is said to take its name from a three-way intersection where roads converging from the Han River, Seoul Station, and the Itaewon district once met. Fact A place name carrying private royal grief, and a place name born from practical traffic geography, sit side by side within a half-day's walk of each other.

Editorial note

Avoid saying "Hyochang Park has always been a public park" — the accurate sequence starts with a crown prince's memorial shrine.
