The Utah Territorial Statehouse, officially Territorial Statehouse State Park Museum, is a state park in Fillmore, Utah. The museum and park preserves the original seat of government for Utah Territory before the capital was moved to Salt Lake City in 1856. Built from 1852 to 1855, the statehouse was initially intended as a larger structure, but only the south wing was completed before the project was abandoned due to lack of federal funding. After its construction, the Utah Territorial Legislative Assembly met in the building for only one full session and parts of two others.
