New Hampshire State Capitol

The New Hampshire State House, built in 1818 in the Greek Revival style, is the oldest state capitol in the United States in which the legislature still meets in its original chambers. The building features an octagonal lantern supporting a gilded dome, crowned by an eagle that rises 150 feet above the streets of Concord. The original wooden eagle was replaced in 1957 with a copper replica.

EverGreene was engaged to restore the dome and eagle, addressing deterioration and reinstating their historic appearance. The team removed failing gold leaf, prepared and primed the metal surfaces, and applied 23.75 karat gold leaf across the 2,300-square-foot dome. Ornamental painting and gilding were also repaired to match the original design intent, ensuring visual continuity across the structure. The original wooden eagle is now preserved inside the State House as a historical artifact, while the restored dome and copper eagle once again define the building’s presence on the Concord skyline.
