Norfolk County consists of twenty-eight eastern Massachusetts communities, mostly located to the South and West of Boston. The County was incorporated as a regional governmental entity in 1793, and has its county seat at the town of Dedham.
The county is not fully contiguous; the towns of Brookline and Cohasset are each part of Norfolk County but are
separated from the majority of Norfolk County (and each other) by either water or other counties. At the county's
formation, Hingham and Hull were to be part of it, but joined Plymouth County instead, leaving Cohasset as an enclave of
Norfolk County. Brookline became an exclave of Norfolk County in 1873 when the neighboring town of West Roxbury was
annexed by Boston (thus leaving Norfolk County to join Suffolk County) and Brookline refused to be annexed by Boston
after the Brookline-Boston annexation debate of 1873.
As reported by the Census Bureau, the county has a total area of 444 square miles (1,150 km2), of which, 400
square miles (1,035 km2) of it is land and 44 square miles (115 km2) of it (10%) is water.
