A capitol is a building or set of buildings that houses government offices, usually the legislative branch. Four structures have served as capitol buildings in the United States. The first was the Maryland State House in Annapolis, Maryland. That building still stands and is currently used to house the Maryland General Assembly. The current United States Capitol is located in the capital city of Washington, D.C.
