Portsmouth NH | USA New Hampshire

Portsmouth is a historic seaport in Rockingham County and New Hampshire’s only deep-water port. Situated on the Piscataqua River, it is the state's oldest settlement (1623) and served as its first capital.

Historical Timeline

The area was originally the home of the Abenaki people. English settlers established "Strawbery Banke" in 1630, named for the wild berries found on the riverbanks. The city became a major colonial hub for fishing, lumbering, and shipbuilding. It hosted the signing of the Treaty of Portsmouth in 1905, which ended the Russo-Japanese War and earned Theodore Roosevelt a Nobel Peace Prize. In the 20th century, the city transitioned from a waning industrial port to a premier cultural and tourist destination, anchored by the preservation of its massive collection of colonial architecture.
