Clad with Indiana limestone, the Capitol has a low, wide base in the plan of a "cross within a square", creating four interior courtyards. The square base is 437 feet on a side and three levels in height. From the center of this base rises a 400 foot domed tower, crowned with the 19 foot tall bronze figure of "The Sower". A thematic progression of ornamentation extends from the principal entrance on the north, westward around the exterior of the building and through the building's interior. The building's exterior stone carvings represent historic events in the 3000 year evolution of democracy as a form of government. The ornamental interior features numerous marble-columned chambers with vaulted polychrome tile ceilings, marble mosaic floors and murals depicting the natural and social history of Nebraska's Native American and Pioneer cultures.
