It is significant for architecture and political history as the seat of state government.","narrative":"Ohio's capitol in Columbus is a limestone Greek Revival building, 504 feet long and 184 feet wide, set in the middle of a landscaped city block. Doric columns mark its entrances, and a conical-roofed cupola rises above a hipped roof. Inside, a central rotunda leads to the House and Senate chambers, with carved wood, marble, paintings and sculpture. Its construction was long and troubled. The cornerstone was laid on July 4, 1839, but the legislature halted work in 1840 and planning resumed in 1844. Henry Walter won the design contest, yet the commissioners turned to New York architect Alexander J. Davis for the design first used. William Russell West, Nathan B. Kelly and Isaiah Rogers later supervised the work. A railroad spur eased the hauling of heavy stone, and the legislature first occupied the building in January 1857. The cupola replaced a planned dome over cost and detail disputes. Despite changing tastes and many hands, the building has long been regarded as a noble structure.","period_of_significance":"1839-1861","architect_builder":"Henry Walter, Alexander J.
