The building housing the museum was built as a post office in 1867 and later served as a Wells Fargo station. Exhibits at the museum reflect Idaho City's heritage as a gold rush town.
Costumed hosts show exhibits and a video depicting Idaho City and the Boise Basin from the time of the Great Gold Rush of the 1860s onward. Artifacts in the museum show all aspects of life in the gold camp.
Hours are daily 11:00 to 4:00 between Memorial Day and Labor Day. The rest of the year, the museum is only open Saturday and Sunday for the same hours. Groups may book the museum at any time.
