Peacefield, also called Peace field or Old House, is a historic home formerly owned by the Adams family of Quincy, Massachusetts.

[1] The two-and-a-half story frame house had a gambrel roof and separate kitchens with quarters for enslaved servants.

In 1787, he sold the estate for £600 to Boston agents acting for John Adams, then in England as the U.S. Minister to the United Kingdom.

His son John Quincy Adams also returned to the house at that time, after completing his ambassadorial term in Berlin.

Brooks Adams, Charles Francis' youngest son, was the last member of the family to live at Peacefield.

Upon his death in 1927, the house became a museum run by the Adams Memorial Society, until it was incorporated into the National Park Service in 1946.

The house contains a variety of valuable furnishings and artifacts which belonged to the four generations of the family that lived there.

The library was built in 1870 by Charles Francis Adams[5] following the wishes of his father John Quincy, who had wanted to protect his books from "accidental conflagration."

The Park now maintains a decorative garden which is largely restored to its appearance in the 1880s in Charles Francis Adams's era.
