Opened to the public in 1991, the American Independence Museum, a non-partisan, non-profit museum, encompasses the 1721 Ladd-Gilman House, a National Landmark property, and the Folsom Tavern, built c. 1775. The permanent collection of documents chronicling the nation’s founding includes an original Dunlap Broadside of the Declaration of Independence and early drafts of the U.S. Constitution. The museum’s mission is to be a premier center for learning about the role that one state, one town, and one family played in the founding of the country and the relevance of the ideals of the American Revolution in every state, every town and every family today.
