Welcome to SEJONG

Located in the heart of the Republic of Korea – about 120 km (75 miles) south of Seoul, Sejong is conceived to relieve overcrowding in Seoul and promote balanced regional economic development. In addition to relocating Korea’s ministries and executive offices from Seoul to Sejong, the Korean government designated Sejong as a center of research, education, and high-tech industry.

Sejong will attract high-tech corporations and research institutes from across the globe. The city is 74-minute away from Seoul and two hours away from other major cities. With green spaces more than half of the city area and a forward thinking energy policy, Sejong will be one of the world’s greenest cities.

To build Sejong, the Korean government established a new government body, the National Agency for Administrative City Construction (NAACC) in 2006 in accordance with the Special Act on Administrative City Construction. In 2015, NAACC successfully finished the relocation of 36 central government organizations and 15 national research institutes to Sejong.


Established in 2006, the National Agency for Administrative City Construction is overseeing the development of the Administrative City in Sejong, a multi-billion dollar project. Read more >>
