Architecture

Interior

From the moment you visit the Iowa State Capitol, the grandeur is evident. Wide, long corridors extend to the North, South, East and West, while rooms and halls are decked in twenty-nine different types of marble (imported from outside of the US), walnut, cherry,butternut, oak and catalpa wood.

Among the features that stand out the most, a grand marble staircase between the third and second floors of the building is very much a focal point. Another central feature is the four-storey public Law Library- which surrounds a central atrium,While most rooms inside the building are home to offices for the Governor, Iowa Treasurer, Auditor of State, Supreme Court Chambers, House of Representatives, Senate and the Secretary of State, there is also a cafeteria and administrative nestled in on the ground floor.

Exterior

Just like the grounds it sits in, the Capitol Building is an elaborate, grand structure. It adopts a rectangular form and Renaissance style- incorporating a central dome built from iron and brick, encased in 23 carat gold leaf. At its peak, the dome measures a staggering 275 feet from top to bottom.

Four other domes surround the rotunda and are equally as well decorated. Although, where their largest neighbour is covered in gold, these four are, instead, copper covered and tarnished green. Adorning the front of the building, limestone from neighbouring states of Missouri, Minnesota and Ohio has been utilised to create elaborate columns and porticoes. The substructure is made from a dark Iowa stone topped by the war-coloured granite that is found in the prairies of the state, while the superstructure is created from sandstone from quarries along the Mississippi river.
