« AT THIS POINT, ON THE OLD CONCORD ROAD AS IT THEN WAS, ENDED THE MIDNIGHT RIDE OF PAUL REVERE. HE HAD, AT ABOUT TWO O'CLOCK OF THE MORNING OF APRIL 19, 1775, THE NIGHT BEING CLEAR AND THE »— Town of Lincoln, Massachusetts, Inscription engraved on the Paul Revere Capture Monument, erected 1895
Your adventure begins at Lexington Green, the initial rallying point for riders Paul Revere and William Dawes after their crossing from Boston on April 18, 1775. It was here that Revere and Dawes began their warning mission to Samuel Adams and John Hancock, who were then sheltering at Reverend Jonas Clarke's home. This site also witnessed the first armed confrontation of the American Revolution on April 19, 1775, just hours after the messengers passed, marking a decisive turning point for the Massachusetts colonies.
Continue to the Clark House, Reverend Jonas Clarke's residence in Lexington, where Samuel Adams and John Hancock were hiding on the night of April 18-19, 1775. Paul Revere and William Dawes delivered their crucial warning about the imminent arrival of British troops. This site, also known as the Hancock-Clarke House, is a direct testament to the events preceding the hostilities, highlighting the urgency and clandestine nature of revolutionary communications. The town of Concord, with its rich heritage, prepared for the impending shockwave.
The route then takes you to the Paul Revere Capture Site, along Battle Road in Minute Man National Historical Park, in Lincoln. It was at this precise location (42.44898935748114°N, 71.27976206053539°W) that, on April 19, 1775, around 1:30 AM, Revere, Dawes, and Prescott were intercepted by a British patrol. Only Samuel Prescott managed to break through the blockade to reach Concord. A circular stone monument, erected in 1895 by the Town of Lincoln with a $100 appropriation, marks the point where Revere's ride ended, a reality less romantic than the legend popularized by Henry Wadsworth Longfellow.
Your exploration continues along Battle Road, the heart of Minute Man National Historical Park. This old Old Concord Road extends for approximately 1.5 km in the Lincoln-Concord area, preserving the battlefield and the escape routes of the Liberty riders. The park offers a visitor center with exhibits on the events of April 18-19, 1775, as well as accessible trails. It was near Hartwell Tavern that Samuel Prescott, after escaping the British, reappeared to warn Captain William Smith, commander of the Lincoln Company of Minute Men, thus mobilizing the local Massachusetts militias.
By the end of the route, you will understand the true scale of these events. After his release by the British, Revere ran through Lexington's Old Burying Ground to rejoin Adams and Hancock, accelerating their escape to Woburn. The Minute Man Monument in Concord, representing the colonial militias, symbolizes the rapid response of Massachusetts' provincial forces. This interactive tour in the Concord and Lincoln area offers a unique perspective on the beginning of the Revolution, far from simplified narratives, and solidifies your understanding of America's 1775 heritage.
