The Wyoming Governor's Mansion, constructed in 1904, is a red brick building of Georgian Colonial architecture. The Mansion is of state-wide political significance as a structure closely related to the functions of the executive branch of government. The Wyoming State Legislature authorized the construction of the Executive Mansion in 1901 and appropriated $3,000 for the purchase of land and $37,000 for construction. The building was officially dedicated in January of 1905. Wyoming's Executive Mansion is the first in the United States to have been occupied by a woman Governor, Nellie Tayloe Ross, who served during the 1920s. The Governor's Mansion opened to the public as a historic house museum in 1977.
