🏆🏆🏆🏆🏆 Chinese Heritage Treasure — Best-preserved Chinese heritage building in Oregon with intact 1887 apothecary and general store

Kam Wah Chung State Heritage Site preserves a remarkable 1860s stone building in John Day that served as the social, medical, and spiritual center of the Chinese community in Eastern Oregon’s gold mining region. The building — originally a trading post — was operated by Ing Hay (a renowned herbalist) and Lung On (a businessman) from the 1880s through 1948. When the building was opened in 1968, the interior was virtually unchanged — containing over 500 Chinese herbal medicines, religious artifacts, preserved food, and personal effects frozen in time for 20 years.
