Sejong-daero: The Symbolic Heart of Downtown Seoul
Running through the Jongno District of downtown Seoul, Sejong-daero (officially Sejong-ro) serves as much more than a mere thoroughfare. Named after the legendary King Sejong the Great of the Joseon Dynasty, this 600-meter stretch of road holds immense symbolic importance for South Korea. It acts as a grand axis, pointing north toward the historic Gyeongbokgung Palace and the majestic Bugaksan and Bukhansan mountains.
As a site once home to royal administrative buildings, the street is steeped in history. Today, it is defined by its monumental statues and its role as a central hub for culture, government, and commerce.

Historical Evolution and Urban Transformation
The landscape of Sejong-daero has undergone significant changes to prioritize public space over vehicular traffic. Historically, the street was a massive 16-lane thoroughfare. However, a major renovation project beginning in 2009 transformed the area to create Gwanghwamun Plaza, a dedicated public open space in the center of the road.
During this 15-month renovation, the road was downsized from 16 lanes to 10 lanes. This project spanned from the front of Gwanghwamun southward to the Sejong-ro intersection, passing the Sejong Center for the Performing Arts. This shift marked a transition from a traffic-heavy artery to a more pedestrian-friendly urban landmark.

Cultural and Ceremonial Significance
The street is home to the statue of Admiral Yi Sun-sin, the renowned naval war hero of Korea. In the past, it was a tradition for Korean Marines nearing the end of their two-year service to gather before his statue to swear their allegiance. This practice was eventually discontinued to alleviate traffic congestion on the street.
In a notable moment for the city's film industry, the Seoul Metropolitan Government granted permission in 2009 for the KBS spy drama Iris to film lengthy action sequences on the plaza. This was a significant move to promote Seoul's major tourist attractions through media.
