Captain Nathaniel Ingersoll lost his fortune shortly after he built this country home, compelling him to sell the property. Ingersoll had constructed a house whose two-story veranda was, like its neighbor Old Green Hill (BR36), in the style of a West Indies plantation house. The arcaded latticework between the portico posts, however, makes the portico on Green Hill much more elaborate. John Lowell Gardner, who acquired the property in 1842, introduced major horticultural improvements to the property. His famous daughter-in-law, Isabella Stewart Gardner (see FL14), made alterations to the house and added an Italian garden, a Japanese garden, and important iris beds to the grounds. Virtually all evidence of her gardens, as well as most of the outbuildings, has been lost with the subdivision of the property in recent years. The land along Warren Street, however, has been put into a conservation trust, which preserves the historic view of the house with its commanding position on the hillside.
