Sejong

Sejong is an administrative capital and smart city in central South Korea that combines government districts with residential zones and green spaces. Wide boulevards run through the city, and tall apartment blocks stand beside low-rise public plazas.

The government laid the foundation in 2007 to ease pressure on Seoul and distribute development more evenly across the country. Ministries and agencies began moving offices from the old capital here starting in 2012.

The name honors King Sejong the Great, who created the Korean alphabet in the 15th century. In the government districts, office workers move between glass towers while parks and pedestrian paths link the public buildings.

Expressways link the city to Seoul in the northwest and Daejeon to the south, so travelers can reach either direction in about an hour. Pedestrians find covered walkways along main streets that shelter from rain and sun.

Sensors along streets continuously measure air quality, temperature, and traffic flow, displaying data on digital boards. Some buses run without human drivers on fixed routes through residential neighborhoods.
