A trading post built in the area in the 1860s along The Dalles Military Road was purchased in 1887 by two Chinese immigrants, Lung On and Ing Hay. They converted the trading post into a clinic, general store, and social center for the community, which continued to operate until the 1940s. In the 1970s the building, then the property of the city of John Day, was converted into a museum called the Kam Wah Chung & Co. Museum. It is now operated in conjunction with the Oregon Parks and Recreation Department and is one of the premier surviving examples of a 19th-century Chinese apothecary shop. It was designated a National Historic Landmark in 2005.
