Sejong Center has been regarded as Korea's representative performance hall. Especially, its pipe organ was the largest in Asia when it opened in 1978. As you are well aware, in Europe, pipe organs were a means of showing off a city's wealth.
I enjoyed THE GREATEST : Thrill, Jeong Dong-ha x Sohyang - Seoul, dated September 17, 2023. and Universal Ballet, The Nutcracker, dated December 28, 2023.
It is easy to reach by using Seoul subway line no.5 Gwanghwamun station, exit no.9. There doesn't seem to be a place to store your winter coat. Instead of a cloakroom, there were unmanned lockers on the 2nd floor but its controling screen was not easy to touch. And I saw several vending machines for water and soda.
For your information, box office will be open 1 hour and 30 minutes before the performance starts. The staff will allow you to come inside to the performance hall in 30 minutes before the performance starts. Enjoy.
