The Iowa State Capitol is the nation?s only five-domed state capitol. It is the government seat of the state of Iowa. It houses the chambers of the Iowa General Assembly. It lies at the heart of capital city of Des Moines, at the intersection of East 9th Street and Grand Avenue.

The building was believed to have been constructed between 1871 and 1886. This capitol was built from limestone quarried from Iowa and nearby states of Missouri, Ohio and Minnesota. Iowa stone was used as base of the edifice?s many porticoes. The capitol?s main feature, which can be seen even from afar, is its shining dome laminated with pure 23-carat gold. From base to dome, the building?s total height is 275 feet, making it one of the tallest structures in the city of Des Moines. The capitol was added to the National Register of Historic Places on October 21, 1976.
