Adams National Historical Park
Adams National Historical Park tells the story of four generations of the Adams family (from 1720 to 1927). The park has two main sites: the Birthplaces of 2nd U.S. President John Adams and 6th U.S. President John Quincy Adams, and Peacefield including the "Old House," home to four generations of the Adams family, and the Stone Library which contains more than 14,000 historic volumes. The website at nps.gov includes information about the park, as well as an informative section on History & Culture.
