By the early 20th century, the building was vacant, decaying and threatened with demolition. During the 1920s, the Daughters of the Utah Pioneers (DUP) proposed restoring the statehouse to serve as a history museum. Under the direction of the Utah State Park and Recreation Commission, the museum opened in 1930 and was placed in the custodial care of the DUP. The statehouse and grounds became a state park in 1957. Today, the Territorial Statehouse serves as a museum which contains many artifacts from the 19th and early 20th centuries. Two restored cabins and a pioneer stone schoolhouse are also located on the grounds.
