It includes the 1878-1880 Queen Anne style Caroline Webster House, a laundry house, a garage, landscape features and camp-related structures.","why_significant":"The property is tied to statesman Daniel Webster, who owned it from 1832 to 1852 and farmed and landscaped it. Its house, designed by Boston architect William Gibbons Preston, is described as the most elaborate Queen Anne house built in Marshfield in the late nineteenth century. The remaining landscape reflects Webster's farming philosophy and nineteenth-century design, and archaeological potential is considered high.","narrative":"This 22.56-acre property on Webster Street in Marshfield, Massachusetts, is the surviving core of a farm first settled by the Thomas family in the 1640s and later developed by Daniel Webster, who owned it from 1832 to 1852 and called it Green Harbor. Webster improved the soil, planted roughly 100,000 trees and built ponds. After fire destroyed his house in 1878, his daughter-in-law Caroline Webster commissioned Boston architect William Gibbons Preston to design a Queen Anne house, completed in 1880 and little altered since. A laundry house of the late 18th or early 19th century also survives. Later owners kept the estate as a memorial to Webster, and since the 1950s part of it has served as a children's day camp. The property was listed for its association with Webster, for the house's design, and for landscape features and likely archaeological remains from several periods of its history.","period_of_significance":"ca. 1772 to ca. 1940","architect_builder":"William Gibbons Preston, architect (Caroline Webster House)","architectural_style":"Queen Anne; Craftsman; No Style","criteria":["B","C"],"status_note":"Western section has been used as a children's day camp since the 1950s; the eastern section is town-owned recreation and conservation land.
