Portsmouth RI | USA Rhode Island

Portsmouth is a coastal town occupying the northern portion of Aquidneck Island, as well as several smaller islands including Prudence, Patience, and Hope Islands. It serves as a primary residential and maritime link between the Newport metropolitan area and the mainland via the Sakonnet River and Mount Hope Bridges.

Historical Timeline

Founded in 1638 by Anne Hutchinson and other dissenters from the Massachusetts Bay Colony, Portsmouth is the second-oldest municipality in Rhode Island. It transitioned through a colonial agrarian phase, a period of British occupation during the American Revolution (1776–1779), and a 19th-century industrial expansion involving coal mining. The 1929 completion of the Mount Hope Bridge and the 1956 construction of the original Sakonnet River Bridge finalized its transition from an agricultural community to a strategic transit and suburban hub.
