« No taxation without representation. »— James Otis, Speech at Faneuil Hall, 1761 (recalled in Writings of James Otis, 1764)
Your journey begins at Faneuil Hall, built in 1742 by merchant Peter Faneuil. This building, funded by a fortune from the slave and rum trade, became the 'Cradle of Liberty.' It was here that the Sons of Liberty, including James Otis and Samuel Adams, delivered fiery speeches against British taxes between 1764 and 1774. The great hall, capable of accommodating 3,000 people within its 40 m x 18 m dimensions, was the scene of the first sparks of the American Revolution. Restored after an 1806 fire by Charles Bulfinch, Faneuil Hall remains a crucial National Historic Landmark for understanding the history of Boston and Massachusetts.
Continue your Boston visit by heading towards the Liberty Tree Site, on Boston Common, America's oldest public park, purchased in 1634 for £30. It was under this tree, commemorated in 1766, that the Sons of Liberty gathered to protest British abuses. Boston Common, covering 20 hectares and bordered by the Freedom Trail, was also the site of British executions and numerous patriotic meetings in the 1760s-1770s. Nearby, the Old State House, built in 1713 as the seat of British colonial government, was the scene of the Boston Massacre on March 5, 1770, where five colonists were killed by British soldiers. From its 15-meter-high balcony, adorned with the British symbols of the lion and unicorn, the Declaration of Independence was first read in Boston on July 18, 1776.
Your quest will then lead you to Granary Burying Ground, a cemetery opened in 1660 and Boston's oldest still in use. Among the 2,345 graves, estimated to hold 5,000 bodies, you will find the resting places of key figures of the American Revolution: Paul Revere (1735-1818), John Hancock (1737-1793), and other members of the Sons of Liberty. Victims of the 1770 Boston Massacre, including Crispus Attucks, are also buried here. Nearby, the Old South Meeting House, a church built in 1729, was the starting point of the Boston Tea Party on December 16, 1773. On that day, Sam Adams and the Sons of Liberty organized a meeting of 5,000 participants to protest the 1773 Tea Act, a major event among Revolutionary War Sites. Its dome, 60 meters high, could accommodate 2,400 people standing.
As you head towards King's Chapel Burying Ground, Boston's oldest cemetery, opened in 1630 with its 1,500 graves, you'll discover a place where the Sons of Liberty held secret meetings before 1770. It is here that Mary Chilton (1607-1679), the first pilgrim woman to disembark from the Mayflower in 1620, is interred. This site, a pioneer of burial vaults in America from the 1700s, offers a perspective on the origins of Boston, Massachusetts. The walk concludes at Old City Hall, built in 1865 in the Second Empire style with its gray Roxbury granite. This imposing 55-meter-high facade features a statue of Ben Franklin (1706-1790), a signer of the Declaration of Independence. The adjacent Parker House Hotel was also a meeting place for the Sons of Liberty before 1775.
Your journey through the monuments of Massachusetts will have allowed you to grasp the spirit of resistance that animated Boston and the colonies. From the speeches at Faneuil Hall to the graves of patriots in Granary Burying Ground, you have followed in the footsteps of Samuel Adams, John Hancock, and Paul Revere. This thematic circuit has revealed the history of Boston, its historic sites, and the legacy of the Sons of Liberty, who shaped the American nation. By deciphering the secret code, you have not just played: you have revisited an essential part of American heritage, an interactive visit that will remain etched in your memory.
