Tallahassee was named Florida's capital in 1824, midway between the then-largest cities in the state, St. Augustine and Pensacola. The first territorial government met in log cabins. A capitol building was constructed in 1826 but never completely finished. It was torn down in 1839 to make room for the erection of the present structure, which was completed in 1845, just prior to Florida’s entry into the United States as the 27th state. Several additions to the historic capitol have been made throughout the years. Frank Millburn made the first expansion in 1902 by adding the classical style dome. In 1923, Henry Klutho additions included two new wings and a marble interior. Finally large wings for the House and Senate chambers were added to the north and south ends of the building in 1936 and 1947, respectively.

The new capitol building was completed in 1977 and the 1845 structure was restored to its 1902 appearance and now serves as a museum.  Architectural highlights include the elaborate art glass dome, red and white striped awnings, and a representation of the Florida State Seal over the entry columns.
