Here's an awesome aerial view of the Iowa State Capitol Building in Des Moines. Des Moines was the site of a small fortress and wasn't incorporated until 1857, in connection with the adoption of a state constitutional amendment moving the capital from Iowa City to a more central location. Construction of the Capitol began in 1871 and took 15 years to complete. It houses the legislature as well as the top executive offices of the Hawkeye State. It's known as the USA's only five-domed capitol.
