In 1773 Daniel Smith married Sarah Michie in North Carolina. Subsequently, he received a land grant from that state. In 1784 the Smiths brought their family to this site and commenced construction on Rock Castle. Much of the construction supervision and plantation management was taken care of by Mrs. Smith, since her husband was gone for long periods on surveying trips. A blend of the Federal and Georgian architectural styles, the house was once the center of a 3,140-acre plantation which today is but 18 acres. In addition to the house, there is a family cemetery and a smokehouse.

Writer Sarah Orne Jewett spent much of her life in this stately Georgian residence, owned by her family since 1819. The view from her desk in the second-floor hall surveys the town's major intersection and provided her with material for her books, such as The Country of the Pointed Firs, which describe the character of the Maine countryside and seacoast with accuracy and affection. In decorating the house for their own use, Miss Jewett and her sister expressed both a pride in their family's past and their own independent, sophisticated tastes. The result is an eclectic blend of 18th-century architecture, antiques, and old wallpapers with furnishings showing the influence of the Arts and Crafts movement.

The house offers tours and educational and recreational programs.
