What Closes on Mondays in Seoul — and What Closes on Tuesdays

European museums close on Mondays because that is when the cleaning, conservation and rehanging happen, and the convention spread until it became a rule of thumb travellers carry everywhere. Korea adopted the same logic and then staggered it.

The Korea Heritage Service, which runs the palaces, deliberately keeps at least one major royal site open on every day of the week. Put Gyeongbokgung and Jongmyo on Tuesday, everything else on Monday, and no visitor arrives to find the whole system shut. It is a sensible piece of administration that almost no guidebook explains, and it is why the standard advice — "museums close on Mondays" — is worse than useless here.

The national museums go further and take no weekly day off at all. The National Museum of Korea, the National Folk Museum, the National Palace Museum and the National Museum of Korean Contemporary History are open every day except 1 January, Seollal and Chuseok. Their maintenance happens on rotating dates instead, which is where the one genuine trap lives.

The National Museum of Korea does close its permanent exhibition halls four times a year: the first Monday of March, June, September and December. The building, the garden and the special exhibitions stay open, so the museum will tell you it is open, and the collection you came for will not be.

In 2026 that catches 2 March, 1 June, 7 September and 7 December. If your Seoul days include one of those, move the museum by a day; the rest of the museum list is unaffected.

The National Folk Museum runs the opposite policy and extends: the last Wednesday, Friday and Saturday of each month it stays open to 21:00. The National Palace Museum and the contemporary history museum both open to 21:00 every Wednesday and Saturday. If your trip is short, those evenings are the cheapest way to buy back the hours a long palace morning eats.

The staggering is a public-sector policy, and the private and municipal institutions did not join in. Leeum Museum of Art in Hannam-dong closes on Mondays, as do New Year's Day, Seollal and Chuseok. The War Memorial of Korea in Yongsan closes on Mondays and opens 09:30 to 18:00 the rest of the week, with the following working day taken instead when a Monday is a holiday. Seoul Museum of Art follows the same Monday pattern.

So the practical shape of a Monday in Seoul is: palaces yes, but only the Gyeongbokgung side; national museums yes; private art museums no. A Monday built around Gyeongbokgung, the two free museums on its grounds and an afternoon in Bukchon loses nothing at all.

A Tuesday is the same trade in reverse: Changdeokgung with a booked garden slot, Changgyeonggung through the connecting gate, and Deoksugung's stone-wall road in the evening, when it stays open to 21:00.

Markets, streets and viewpoints run on their own clocks and ignore the museum week entirely. Gwangjang Market's food alleys, Namdaemun's lanes, the shopping floors of Myeongdong, the walk along Cheonggyecheon, the Han River parks and the Seoul City Wall trails are all available on any day.

So are the paid views: N Seoul Tower runs 10:30 to 22:30 on weekdays and 10:00 to 23:00 at weekends, all year; Seoul Sky at Lotte World Tower runs 10:30 to 22:00, to 23:00 on Fridays, Saturdays and public holidays, also all year. Lotte World's theme park is open every day, weather permitting.

That gives every closed day an obvious substitute. The one thing you cannot substitute is the Huwon garden slot at Changdeokgung, which exists only on days the palace is open and only at published session times — so if your trip has one plausible garden morning, check the day of the week before you build anything else around it.

When a closing day lands on a public holiday, the palaces open anyway and take the next non-holiday day off instead. That means a holiday Monday is a good palace day, and the Tuesday after it is not.

The fixed closures that catch everyone are the two big family holidays. On Seollal, the lunar new year, and on Chuseok in autumn, the national museums shut for the day itself and the palaces run reduced programmes; special viewings such as Gyeongbokgung's Gyeonghoeru sessions stop for the whole holiday block, which in 2026 runs from 24 to 27 September.

The city itself does not shut. Trains run, convenience stores stay open, and central Seoul empties as families travel — which is why holiday weeks are, for a visitor, some of the least crowded days of the year in the palaces that stay open. The seasonal picture is on the when-to-visit page.

Seoul closes fewer doors at night than most large cities, so a day that starts badly can still be rescued after five.

Deoksugung and Changgyeonggung both run to 21:00 every day of the year they are open, with last entry at 20:00. That is genuinely unusual — most royal sites anywhere shut in the late afternoon — and it makes Deoksugung the palace to keep for the end of a day rather than the start. Its stone-wall road is lit, and the changing of the guard at its own gate runs during the day.

Among museums, the National Palace Museum and the National Museum of Korean Contemporary History both open until 21:00 on Wednesdays and Saturdays; the National Museum of Korea does the same; and the National Folk Museum extends to 21:00 on the last Wednesday, Friday and Saturday of the month. The last Wednesday is Korea's Culture Day, which is the single best evening in the month for anyone whose daylight hours went wrong.

Above all this sit the two towers, both open past 22:00 every night, and both worth more after dark than before. If a closure has eaten an afternoon, the honest fix is usually N Seoul Tower or Seoul Sky rather than a rushed museum.

If the day you have landed on is the wrong one for the site you wanted, the fastest recovery is usually a change of district rather than a change of plan.

Around Gwanghwamun and Jongno the palaces dominate, and on their closed days the two free museums on the Gyeongbokgung grounds, Insadong's tea houses and the Cheonggyecheon walk carry the morning on their own.

In Yongsan, the National Museum of Korea never takes a weekday off, and Itaewon's restaurants keep their own hours, but the War Memorial and Leeum both shut on Mondays — so Yongsan is a poor Monday and an excellent Tuesday.

East of the river, Jamsil is closure-proof: Lotte World, Seoul Sky and the aquarium all run seven days. So is Dongdaemun's design plaza, which does its business in the evening anyway, and every market in the city, whose own rest days are Sundays and lunar-calendar dates rather than Mondays. Those market rest days are listed with the markets, and they are the one closure pattern in Seoul that has nothing to do with museums.
