Wyoming State Capitol, State Capitol building in Cheyenne, United States
The Wyoming State Capitol is a government building in Renaissance Revival style located on 24th Street in Cheyenne. Its central dome rises 141 feet (43 meters) above the ground and forms the tallest element of the complex, while the floor plan is complemented by side wings and a columned portico.
Architect William DuBois designed the structure, which began in 1886 and was completed in 1890, coinciding with Wyoming's transition from territory to statehood. Later expansions added wings in the 1910s and 1970s to accommodate the growing needs of state administration.
The name comes from the Wyoming Territory, established in 1868 and named after a Lenape term meaning large plains. Visitors today can view paintings and sculptures inside that depict scenes from early settlement and pioneer life.
The building is open Monday through Friday from 8 AM to 5 PM, with free self-guided tours available through the main areas. Visitors should bring valid identification and note that some rooms may be inaccessible during active sessions.
The rotunda preserves the original decorative painting from 1888, carefully restored during the 2019 renovation. At the same time, micropiles were installed beneath the foundation to strengthen the structure without altering its historic appearance.
