Portsmouth

It is the fourth-largest community in the county, with a population of 20,784 at the 2000 census. A historic seaport and popular summer tourist destination, Portsmouth is served by Pease International Tradeport, a former military base converted into a civilian airport and office park.

In 2008 Portsmouth was named one of the "Dozen Distinctive Destinations" by the National Trust for Historic Preservation.

Portsmouth shipbuilding history has a long symbiotic relationship with Kittery, Maine, across the Piscataqua River. Although John Paul Jones boarded at the Portsmouth house which now bears his name, his ship Ranger was built on Badger's Island in Kittery. The Portsmouth Naval Shipyard, established in 1800 as the first federal navy yard, is located on Seavey's Island in Kittery. President Theodore Roosevelt arranged for the base to host negotiations leading to the 1905 Treaty of Portsmouth, ending the Russo-Japanese War.
