Adams National Historical Park, formerly Adams National Historic Site, in Quincy, Massachusetts, preserves the home of United States presidents John Adams and John Quincy Adams, of U.S. envoy to Great Britain, Charles Francis Adams, and of writers and historians Henry Adams and Brooks Adams. The national historical park's eleven buildings tell the story of five generations of the Adams family (from 1720 to 1927) including presidents, first ladies, envoys, historians, writers, and family members who supported and contributed to their success. In addition to Peacefield, home to four generations of the Adams family, the park's main historic features include the John Adams Birthplace (October 30, 1735), the nearby John Quincy Adams Birthplace (July 11, 1767), and the Stone Library (built in 1870 to house the books of John Quincy Adams and believed to be the first presidential library), containing more than 14,000 historic volumes in 12 languages. There is an off-site Visitors Center less than a mile (1.6 km) away. Regularly scheduled tours of the houses are offered in season (April 19 to November 10) by guided tour only. Access to United First Parish Church, where the Adamses worshipped and are buried, is provided by the congregation, for which they ask a small donation. The Church of the Presidents is across the town square from the Visitors Center and provides tours on a regular basis.

The younger Adams lived here until 1764, when he married Abigail Smith. It is a few feet from the John Quincy Adams Birthplace home, where John and Abigail Adams moved. John Quincy Adams Birthplace The house where John and Abigail Adams and their family lived during the time he was working on the Declaration of Independence and the Revolutionary War is also the 1767 birthplace of their son, John Quincy Adams. The younger Adams grew up in the home, and he and his family lived in it for a time later in life.
