서울 구 용산철도병원 본관

Old Yongsan Railway Hospital Main Building (now Yongsan History Museum) is a preserved colonial-era institutional building in Seoul's Yongsan-gu, originally built as the main building of the Yongsan Railway Hospital that served the Imperial Japanese-operated railway system in colonial Korea. The building has been preserved as a registered modern cultural property and converted into the Yongsan History Museum, which walks visitors through Yongsan's modern history — from colonial-era institutional development through the Korean War period and post-war urban transformation — alongside period documents, archival photographs, and interpretive panels. Best for travelers seriously interested in modern Korean institutional-and-architectural history.
