Portsmouth is an independent city in the Commonwealth of Virginia. As of the 2010 census, the population was 95,535. It is part of the Hampton Roads metropolitan area.The Norfolk Naval Shipyard, often called the Norfolk Navy Yard, is a historic and active U.S. Navy facility that is actually located in Portsmouth rather than Norfolk; the original name "Gosport" was changed to "Norfolk" to reflect its location in what is now the former Norfolk County, Virginia. The shipyard upgrades, remodels, and repairs ships of the US Navy and is one of the few facilities in the world with the capability to dry dock an aircraft carrier.Directly opposite Norfolk, the city of Portsmouth also has miles of waterfront land on the Elizabeth River as part of the harbor of Hampton Roads. There is a ferry boat that takes riders back and forth across the water between Downtown Norfolk and Olde Towne Portsmouth.
