Winterthur Farms, Intersection State Routes 92 & 100, Intersection State Routes 92 & 100, Winterthur, New Castle County, DE

Significance: This intersection is surrounded by a rural landscape and buildings, structures, objects and sites once functionally-related to Winterthur Farms and one branch of the de Pont family. Winterthur Farms, a nationally-recognized model estate farm was developed under the stewardship of Colonel Henry Algernon du Pont (b.1838, d.1926) and later his son, Henry Francis du Pont (b.1880, d.1969), following academic professional landscape design standards, and scientific, agricultural, and farming philosophies of the late-nineteenth and early-twentieth centuries. Winterthur Farms demonstrates the evolution of a traditional eighteenth- and nineteenth-century vernacular rural landscape modified through extensive intervention and capital improvements into a great agricultural estate in the late-nineteenth and early-twentieth centuries.
