Wonju History Museum's official facilities page gives the address as 134 Bongsan-ro, Wonju, Gangwon Province, opening hours 9 a.m.–6 p.m., last entry at 5 p.m., and free admission. It lists closures on Mondays, January 1, Lunar New Year, Chuseok and the day after a public holiday.
The museum specifically notes limited parking capacity and recommends public transport. The first lot has 24 car spaces, while the second has eight car spaces and two bus spaces, for 32 officially listed car spaces in total. This is design capacity, not live availability.
The first floor includes a history gallery, Hyeonseok gallery and temporary exhibition area; the second has a folk-life gallery and an exhibition devoted to artisan Ilsa Kim Bong-ryong. A traditional Korean house is also included among the museum facilities. Check current temporary exhibitions and parking before travelling. Contact 033-737-4371.
