A feature of the State Capitol building is its huge gold-painted wooden eagle, which was raised to the top of the dome in 1818. Several additionas were completed through 1909 when the Governor and his Council then employed architects under whose plans the entire building was remodeled precisely as it is today. The building has been made fire-proof in all its parts, providing electric elevators, modern lighting, vaults, and an up-to-date heating system. A Capitol Annex was added in 1938, which is connected to the Capitol building by an underground tunnel.
