Gloucester is a city on Cape Ann in Essex County, Massachusetts, in the United States. It is part ofMassachusetts' North Shore. The population was 28,789 at the 2010 U.S. Census.
The boundaries of Gloucester originally included the town of Rockport, in an area dubbed "Sandy Bay". That village separated formally on February 27, 1840. In 1873, Gloucester was reincorporated as a city.Gloucester was founded at Cape Ann by an expedition called the "Dorchester Company" of men from Dorchester (in the county of Dorset, England) chartered by James I in 1623. It was one of the first English settlements in what would become the Massachusetts Bay Colony, and predates both Salem in 1626 and Boston in 1630. The first company of pioneers made landing at Half Moon Beach and settled nearby, setting up fishing stages in a field in what is now Stage Fort Park. This settlement's existence is proclaimed today by a memorial tablet, affixed to a 50-foot (15 m) boulder in that park.
