city, Suffolk county, Massachusetts, U.S. It lies along Massachusetts Bay just northeast of Boston. First known as Rumney Marsh, it was settled in 1626 and was part of Boston from 1632 until 1739, when it became part of Chelsea. During the American Revolution, the British schooner Diana, seeking food supplies, was destroyed in the locality by Chelsea patriots led by Israel Putnam at the so-called Battle of Chelsea Creek (May 27, 1775). Separately incorporated as the town of North Chelsea in 1846, it was renamed in 1871 to honour Paul Revere.
