The first State House was constructed in 1808 by Sylvanus Baldwin and was replaced by a larger iteration, designed by Ammi B. Young, between 1833 and 1838. Young’s design was a reserved Greek Revival design based upon the Temple of Hephaestus in Athens, Greece.
The second State House was nearly destroyed in a fire in January 1857, with only the portico and granite walls salvageable.
In the design of the third State House, Silloway added an additional bay of windows on each side of the central portico and increased the height of the central dome. The dome was topped with a statue named Agriculture, a representation of Ceres, an ancient Roman goddess of agriculture. It was carved by Vermont artist Larkin Goldsmith Mead.
The Vermont State House underwent extensive renovations in the early 1980s, led by curator David Schütz.
