American Revolution in Massachusetts

Dorchester Heights Monument

From 1926 to 1927 New York and Massachusetts placed markers along the route taken by the artillery train in commemoration of the 150th anniversary of the expedition, calling it the Henry Knox Trail. 

Evacuation Day began being celebrated in 1901, and was made an official holiday for Suffolk County in Massachusetts in 1938. The parade held on or around that day in South Boston every year is meant to also commemorate Evacuation Day, as the route normally goes past Dorchester Heights.

A monument commemorating the fortification on Dorchester Heights was erected in 1902. Dorchester Heights was also added to the National Register of Historic Places in 2001, and is now overseen by the National Park Service.
