The square, which has been expanded and partially refurbished into a park, opened to the public at 11 a.m., according to the Seoul city government.
Construction began in November 2020 to expand the square with new historical and cultural attractions.
The square is now 2.1 times larger than before at 40,300 square meters after an adjacent road that had been located to its west was covered.
Over 5,000 trees have been planted across the square, with around a quarter of it covered by greenery.
A performance spot has also been installed in front of the Sejong Center for the Performing Arts.
The square also includes a new 40-meter-long tunnel fountain as well as a 53-meter media wall near the Sejong Center.
An opening ceremony will kick off at 7 p.m., with a performance by a civic orchestra, followed by various popular artists, including alternative pop band Leenalchi and K-pop girl group Oh My Girl.
Sejong-daero, which runs next to the square, will be closed off from 6 p.m. to 10 p.m. for the event. (Yonhap)
