Assay Office, Federal office building in downtown Boise, United States.
The Assay Office features thick sandstone walls, barred windows, and a special ventilation cupola designed for processing precious metals and minerals.
Constructed in 1871 as one of seven federal assay offices in the United States, this facility processed over 1.5 million dollars in gold annually.
The building reflects the economic transformation of Idaho Territory through its architecture and role in managing the region's mineral resources.
Located at 210 Main Street, the building now houses the State Historical Preservation Office and Archaeological Survey of Idaho.
The building contained specialized equipment for mineral processing on the first floor, with living quarters for the chief assayer on the second floor.
