Part of today's Minute Man National Historic Park, it is associated with the revolution's first battle, the 1775 battles of Lexington and Concord. Believed to have been built in 1692 (or possibly a decade or so earlier), in what was then Concord, it is believed to be the oldest house in Lincoln.It is located on North County Road, just off Battle Road (formerly the Bay Road), a few hundred yards east of the Hartwell Tavern and the contemporary Samuel Hartwell House. Its first known occupant was yeoman Benjamin Whittemore (d. 1734). It was latterly the home of Captain William Smith (1746–1787), commanding officer of the Lincoln minutemen and the only brother of Abigail Adams, wife of the prominent patriot John Adams. The house has been restored by National Park Service to look as it would have in 1775.William and Elizabeth Dodge purchased the home as a rental property in 1758. When they moved to New Hampshire, they gave the house to their only daughter, Catharine Louisa Salmon. Catharine married William Smith in 1771. The couple lived in the house with their three children: Elizabeth, Louisa Catharine and William Jr. Their African slave, Cato, is not believed to have fought in the battles of Lexington and Concord, but on April 24, 1775, he enlisted as a soldier in Smith's newly formed company in the 6th Massachusetts Regiment commanded by Colonel John Nixon. He died in New Castle, New York, in January 1777.Smith died in Philadelphia on September 3, 1787, aged 40, after abandoning his wife and (now six) children and becoming an alcoholic.

The house had a series of owners before it was added to the Minute Man National Historic Park in 1975. (Manuel Silva purchased the property in 1924. A hog farmer, Silva had about four hundred swine at the time of his 1945 death. It is believed his wife divided the interior into four apartments around 1956.)
