In the heart of Concord, the New Hampshire State House was designed in 1814 by architect Stuart James Park. One notable feature of the building’s architecture is the difference in windows. From the first floor, the building has rectangle, arched, square, and partially arched windows with small round windows on the golden dome. This building is said to be “The nation’s oldest state house in which the legislature still occupies its original chambers,” which is inscribed in the granite entrance.
