Hurshimchung

Hurshimchung (Heosimcheong) is a vast urban hot spring complex in Oncheon-dong, Dongnae District, Busan, occupying about 4,300 m² across five floors and accommodating up to 3,000 bathers at a time. The alkaline spring water, which emerges at temperatures between roughly 45°C and 56°C, is noted for having the highest magnesium concentration of any hot spring in Korea. The site is said to have been used by kings of the Silla Dynasty over a thousand years ago; the current building dates to 1991 and today draws around four million visitors a year to its roughly forty bath types, saunas (including a 0°C 'igloo' room), mud baths, and connected leisure facilities.
