Incheon Gaehangjang Modern Architecture Exhibition Hall is a modern architecture exhibition hall in Incheon's Chinatown. It displays models of buildings constructed in Incheon after the port opened, currency models, and old objects, and explains modern architectural styles. The exhibition hall uses the former Japanese 18th Bank building, retaining the exterior of its one-story stone structure completed in 1903. The exhibition hall is small and can be seen quickly.
