Formerly known as Ashdale Farm, the Stevens-Coolidge Place was the summer home of John Gardner Coolidge and Helen Stevens Coolidge from 1914 to 1962. Mr. Coolidge, a descendant of Thomas Jefferson and nephew of Isabella Stewart Gardner, was a diplomat. Helen Coolidge devoted herself to preserving and improving Ashdale Farm, which her family had first acquired in 1729 and subsequently farmed for six generations. Between 1914 and 1918, preservation architect Joseph Everett Chandler remodeled the two connected late-Federal period farmhouses. The house’s collections include Chinese porcelain and other Asian artifacts, American furniture, and American and European decorative arts, reflecting the Coolidges’ wide-ranging interests and frequent trips abroad. Chandler also enhanced the design of the landscape, which eventually included a perennial garden, a kitchen and cut flower garden, a rose garden, a French potager garden with a brick serpentine wall, and a greenhouse complex. Intermingling with the formal gardens are rustic elements, including hay fields, an orchard, and extensive woodlands.
