There are 351 properties and districts listed on the National Register in the county, including 58
National Historic Landmarks. The city of Boston is the location of more than 300 of these properties and districts, including 57
National Historic Landmarks; they are listed separately. Properties and districts located in the county's other three municipalities are listed here.
For reasons of length, the Boston list has been split into northern and southern listings, divided by the
Massachusetts Turnpike. Northern Boston has 149 of these listings, including 39 districts, 48 landmarks, and three
National Historic Landmark Districts. Southern Boston, including locations in
Boston Harbor, has 181 listings, including 46 districts, 12 landmarks, and one
National Historic Landmark District. Two historic districts overlap into both northern and southern Boston: milestones that make up the
1767 Milestones are found in both areas, and the
Olmsted Park System extends through much of the city.
