Cascade County Courthouse, County courthouse in Great Falls, United States

The Cascade County Courthouse is a grey sandstone building on a full city block in Great Falls, Montana, built 1901–1903. Its copper dome, replacing a planned stone one, is topped by a 14-foot statue of Justice. The sandstone was quarried within six miles of the site.

Cascade County was founded in 1887 and conducted its business from several office buildings in Great Falls. The county bought the full city block site in 1891 for $20,000, but tax revenue was too low to build until a decade later; the courthouse was erected in 1901–1903. The grey sandstone came from quarries within six miles of the building, and a planned stone dome was replaced by a copper one.

The courthouse's 14-foot statue of Justice crowns a copper dome that was used during World War II as a lookout for Japanese aircraft. The dome replaced a planned stone one, and the grey sandstone below was quarried within six miles of the building.
