Blue Square

Leeum Museum of Art

An art museum run by the Samsung Foundation of Culture. The standing exhibition of historic Korean art is free and the special exhibitions are ticketed, priced per show rather than at a standing rate. From exit 1 of Hangangjin Station, the route runs 100 metres towards Itaewon, then turns right into the first alley for an uphill walk of about five minutes.

N Seoul Tower

Time the visit around sunset if you want both daylight and night views, and plan the ascent separately from the observatory ticket.

Namsangol Hanok Village

Five hanok moved onto the northern slope of Namsan beside Chungmuro Station, with a traditional garden laid around them. The houses open Tuesday to Sunday and rest on Mondays; closing time differs by an hour between summer and winter. There is nothing to pay at the gate.

War Memorial of Korea

Closes at 17:40, not 18:00, and stops admitting visitors at 17:00 — a 40-minute gap that catches people who arrive after an afternoon elsewhere. Closed Mondays, and when a holiday falls on a Monday the closure moves to the day after, which is the rule most itineraries miss.
