Peacefield is a historic home formerly owned by second United States President John Adams and other members of the Adams family, located in Quincy, Massachusetts. It is now part of the Adams National Historical Park. The oldest portion of the house was built in 1731 by Leonard Vassall, a sugar-planter from Jamaica, and acquired by John and Abigail Adams in 1787. The Adams were at that time still resident in London, but returned in 1788 to occupy the house and its 40 acres of farmland and orchards.
