A−
HistoryA character grade: shown, never part of Portsmouth’s overall grade.
Rhode Island towns list more on the Register than most of the country (a typical Rhode Island town has 94.7 per 10,000 residents, the U.S. 2.4), so Portsmouth’s 13.6 sits below most of its state (11% of Rhode Island towns have fewer) while its 24 historic buildings outnumber those of 80% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A−. The pre-1940 share is a Census survey estimate (±3.1 points). Two sources give 1638.

The country’s official list of buildings and places worth saving. One is a National Historic Landmark, the highest tier.
Portsmouth was settled in 1638 by a group of religious dissenters from Massachusetts Bay Colony, including Dr. John Clarke, William Coddington, and Anne Hutchinson. It is named after Portsmouth, Hampshire, England. Roger Williams convinced the settlers that they should go there instead of settling in the Province of New Jersey, where they had first planned on going.
It was founded by the signers of the Portsmouth Compact. Its original name was Pocasset and it was officially named Portsmouth on May 12, 1639. It became part of the Colony of Rhode Island and Providence Plantations (see Aquidneck Island) and eventually part of the State of Rhode Island and Providence Plantations.

about one and one-half miles farther south, on the east side of the island which they called Newtown. There they laid o«ut house lots for a numerous settlement, but the speedy division of the island into farms soon absorbed all the population then in Portsmouth, and the settlement at Newport this year attracted a large portion of the emigrants to that locality.
