Dorchester Heights is the central area of South Boston. It is the highest area in the neighborhood and commands a view of both Boston Harbor and downtown.


Dorchester Heights was and is remembered in American history for an action in the American Revolutionary War known as the Fortification of Dorchester Heights. After the battles of Lexington and Concord, Revolutionary sentiment within New England reached a new high, and thousands of militiamen from the Northern colonies converged on Boston, pushing the British back within what were then relatively narrow city limits. In June 1775 British soldiers under General William Howe attacked and seized Bunker Hill, but in the process sustained many losses. Following this encounter, the Continental Congress in Philadelphia gave George Washington the title of commander-in-chief and sent him to oversee the Siege of Boston.

The stalemate in Boston lasted for months, only breaking when Colonel Henry Knox returned from Fort Ticonderoga in New York, having led a team of sleds loaded with tens of thousands of pounds of artillery (cannon) in winter from the fort across hundreds of miles to Boston. This added artillery gave Washington the firepower needed to make a decisive move. On the night of March 4, 1776, as 800 American soldiers stood guard along the river of Dorchester shores, 1,200 American soldiers occupied Dorchester Heights. They began working through the night to build structures suitable to defend against the British Army. A large portion of the artillery, pulled by oxen, was moved and installed, without being noticed by the British, at Dorchester Heights, a point of strategic importance due to its elevation and commanding view of all of Boston and Boston Harbor.

In response, Howe planned a counteroffensive to take the fortified positions on the Heights, but bad weather forced him to reconsider. The Royal Navy evacuated the British Army from Boston on March 17, 1776, along with many Loyalists. March 17th is observed as the holiday Evacuation Day in Suffolk County, Massachusetts.

The Dorchester Heights Monument was completed in 1902 to designs by Boston architects Peabody and Stearns. It is 115 feet (35m) tall, built of Georgia white marble capped with octagonal cupola and weather vane, and is generally reminiscent of a church steeple in the Federal style. The monument is now operated by the National Park Service as part of Boston National Historical Park.

Panoramic fireworks displays on the Fourth of July[edit]

Dorchester Heights is one of the highest natural geographical locations in greater Boston, and affords panoramic views of many communities to the south and west of the city. This view is of particular interest on July 4, where after sunset one can watch the official fireworks from over a dozen communities, along with countless amateur displays, as they unfold on the horizon over the course of the evening.
