The Freedom Trail® Foundation markets, promotes, and helps to preserve the Freedom Trail through tourist services and activities, educational programs, and marketing and public relations efforts. Marked by a red line on city walkways, Boston’s iconic 2.5-mile Freedom Trail connects 16 of America’s most significant historical landmarks. The Foundation’s Preservation Fund helps support preservation, rehabilitation, and capital projects for Freedom Trail sites which help avoid, minimize, or mitigate adverse effects of the elements and manmade wear and tear of Boston’s precious 17th, 18th, and 19th century sites.
