About this property
The Assay Office is a historic building at 210 Main Street in Boise, Idaho. It is significant for its role in the history of mining in Idaho, and was the first major federal government building in the Idaho Territory. During the first half of the 1860s, Idaho's gold production was the third highest in the nation. Due to the difficulty of transporting ores, which can be heavy, the long distance to the nearest U.S. Mint in San Francisco, there was great demand for an assaying office in Idaho that would be able to separate precious metals from impurities in them, helping to place a value on ores that went through the office.

The National Register of Historic Places, administered by the National Park Service, is the United States federal government's official list of districts, sites, buildings, structures, and objects deemed worthy of preservation for their historical, architectural, archaeological, engineering, or cultural significance. Listing on the National Register recognizes a property's importance to American history but does not place restrictions on private owners; it does, however, make properties eligible for federal historic preservation tax incentives and enables consideration in federal planning decisions. National Historic Landmark designation, the highest level of federal recognition, is reserved for properties that possess exceptional national significance in the history, architecture, archaeology, engineering, or culture of the United States. This property is recorded in the National Register under reference number 66000305. It was listed on October 14, 1966.
