Harbor is a natural harbor and estuary of Massachusetts
Bay, and is located adjacent to the city of Boston, Massachusetts. It is home to the Port of Boston
, a major shipping facility in the northeast.
Since its discovery by John Smith in 1614, Boston Harbor has been an important port in American history. It was the site of the Boston Tea Party as well as almost continuous backfilling of the harbor until the 19th century. By 1660 almost all imports came to the greater Boston area and the New England
coast through the waters of Boston Harbor.
Boston Harbor is a large harbor which constitutes the western extremity of Massachusetts Bay. The harbor is sheltered from Massachusetts Bay and the open Atlantic Ocean by a combination of the Winthrop
Peninsula and Deer Island to the north, the hooked Nantasket Peninsula and Point Allerton to the south, and the harbor islands in the middle. The harbor is often described as being split into an inner harbor and an outer harbor.The harbor itself comprises fifty square miles with 180 miles (290 km) of shoreline and 34 harbor islands.
- The inner harbor was historically the main port of Boston and is still the site of most of its port facilities as well as the Boston waterfront, which has been redeveloped for residential and recreational uses. inner harbor extends from the mouths of the Charles River
and the Mystic River
, both of which empty into the harbor, to Logan International Airport and Castle Island
, where the inner harbor meets the outer harbor.
- The outer harbor stretches to the south and east of the inner harbor. To its landward side, and moving in a counterclockwise direction, the harbor is made up of the three small bays of Dorchester Bay, Quincy
Bay and Hingham
Bay. To seaward, the two deep water anchorages of President Roads and Nantasket Roads are separated by Long Island.
