It contains former homes of influential families such as the Cabots, Perkinses, Sargents and Gardners. It also holds some of the town's oldest and most architecturally distinguished houses and notable designed landscapes.","narrative":"Green Hill is a neighborhood of about 70 acres in Brookline, Massachusetts, centered on Warren Street, Cottage Street and part of the former Sargent estate. Its roughly two dozen houses range from late 18th-century farmhouses to early 20th-century residences, many set on large landscaped lots. Three summer homes in the West Indies style, with overhanging roofs on light columns, are the most notable buildings, alongside Federal and Gothic Revival houses and the 1845 stone Sargent house attributed to Richard Upjohn. Land here passed from early colonial allotments to Brookline farmers, then in 1793 to merchant George Cabot, beginning a wave of wealthy Boston merchant families who built summer homes. The area also has a strong horticultural tradition, including the Holm Lea estate of Ignatius and Charles Sprague Sargent and landscape work linked to the Olmsted firm. Narrow winding roads, stone walls and preserved plantings keep its 19th-century feel.","period_of_significance":null,"architect_builder":"Richard Upjohn (attributed, 209 Sargent Road); John Charles Olmsted (12 Fairmount Street); Chapman and Frazer (45 and 75 Cottage Street); George Harvey (278 Warren Street); E.A.
