The Maine State Building is a historic building on Preservation Way, part of the Poland Springs resort complex in South Poland, Maine. It was built in 1893 at the Columbian Exposition in Chicago. Designed by Chicago architect Charles Sumner Frost, a Lewiston, Maine native and MIT graduate, the building was constructed of granite with a slate roof. All the materials were from Maine and crafted by craftsmen and companies from Maine. At the fair, the building was filled with displays about the State of Maine.
