Montpelier, Vermont Vermont State House, Montpelier, VermontI was not able to see the inside of the dome because this building has no rotunda – just wood supports inside the dome. Statue of Ethan Allen at the Vermont State House.Ethan Allen was an American Patriot. He was instrumental in helping American General Benedict Arnold (before Arnold turned traitor) capture Fort Ticonderoga in the Revolutionary War. He was also one of the founders of the state of Vermont. He was also a bit of a wild character – worth a little study if you have time! Vermont House Chamber. Vermont Senate Chamber.
