MMCA Seoul
A contemporary art stop beside the palace, with enough space to make one exhibition the centre of your afternoon.
Notes from the citySeoul
A free museum day does not mean every building is open. Plan the 2026 holiday around the actual dates and the visit you want.

For MMCA Seoul, the useful dates are 24, 26 and 27 September: admission is free, but you still need a ticket. The museum closes on Chuseok day, 25 September. Leeum and the National Museum of Korea also list a closure that day.
The palace’s Chuseok notice makes ordinary daytime admission free from 24 to 27 September. Its autumn night programme is a separate ticketed visit. At Leeum, free access to the permanent collection does not include every special exhibition.
Start with the date, choose the exhibition or collection, and check the linked official notice before travelling. Restaurant holiday service and club admission follow their own rules. The useful plan is the one whose doors will actually be open.
A contemporary art stop beside the palace, with enough space to make one exhibition the centre of your afternoon.
Three free-admission dates for the Seoul museum over Chuseok. Choose a show and collect a ticket before going into the galleries.
Korean antiquities and contemporary ideas share a hillside address. Make the collection or a special exhibition your starting point.
Give a few galleries your full attention, then step outside. A free permanent collection and a generous setting beside Yongsan.
Go through Gwanghwamun and let the courtyards set the pace. The palace is a different experience in daylight and after dark.
Go back to the palace after sunset. The announced autumn night season runs on selected evenings through 2 October.
