This 1737 house was a parsonage during the 18th century in Lexington, Mass., and was home to Rev. Jonas Clarke.

In the wee hours of April 19, 1775, John Hancock and Samuel Adams were guests at the home when Paul Revere rode into town with his famous warning that the British were coming. The events that ensued — the Battles of Lexington and Concord — were the opening events of the Revolutionary War.

John Hancock was a cousin to Clarke’s wife, Lucy, and the first signer of the Declaration of Independence. The house now serves as a museum.
