The Old State Capitol Building entrance and dome as seen past its entry gate and vintage lights in Springfield, Illinois. The structure was built in the Greek Revival style in 1837–1840, and served as the state house from 1840 to 1876 and was the site of the candidacy announcement by Abraham Lincoln in 1858. In order to restore and preserve the Old State Capitol, which had been extensively altered during its life as a courthouse, it was completely dismantled, stone by stone, and rebuilt. The public areas of the Old State Capitol were reconstructed to resemble the appearance of the building in 1860, when Lincoln last saw the capitol prior to his departure to Washington to assume the presidency. The structure is listed on the National Register of Historic Places.
