For almost two decades, Idaho's territorial government was housed in various private buildings around downtown Boise. After failed efforts to get the federal government to fund a capitol building, the territorial legislature finally agreed in 1885 to appropriate $80,000 for a territorial capitol. The red-brick structure, located on the block between Jefferson and State and Sixth and Seventh streets, served not only the last four years of territorial government (1886-1890) but the first twenty-two years of statehood. In 1905, as the state's population mushroomed with the advent of federally funded irrigation projects, a Capitol Building Commission was authorized. The Boise architectural firm of J. E. Tourtellotte and Company won the competition to design the new capitol; construction began in the summer of 1906, The capitol's central section was completed late in 1912, and offices were moved over at that time. The 1913 inauguration of Gov. John M. Haines was held in the new building. Tourtellotte and Hummel-successor to the original firm-had already been awarded a contract to design east and west wings. Their construction began in1919; the whole capitol was completed by the end of 1920. A replica of our nation's capitol, this is the only statehouse in America with a geothermal heating system, fed by naturally hot water from deep in the ground.
