Capitol is a term that was first applied to the Temple of Jupiter on the Capitoline Hill, Rome, completed in 507 BC. It was destroyed several times by fire and rebuilt. The existing Capitol, a large portion of which serves the purpose of a museum, was erected from designs by Michelangelo. In all the chief cities of the ancient Roman Empire there was a capitol or town hall. In the United States the building occupied by Congress at Washington bears the name of the Capitol, and the halls of the legislative assembles of the different states are so named.
