Liberty Hall
New Jersey Historical Commission
1. Liberty Hall Marker
Liberty Hall was built in 1772 for William Livingston, New Jersey’s first elected governor, member of the Continental Congress, and signer of the U.S. Constitution. From 1811-1995, Liberty Hall was home to the politically influential Kean family whose members served as U.S. Senators and Representatives as well as New Jersey State Assemblypersons and Governor. In the 20th century, Mary Alice Barney Kean's historic preservation work laid the groundwork for the home to become a public museum. The museum today shares the history of all those who lived and labored in the home, both free and enslaved.
