estate, and was moved to its present location in the 20th century after the city took part of the estate by eminent domain for another road project. Lyman made a number of changes to the landscaping of the estate, including the construction of a formal garden area to the north of the main house. The estate next passed through a succession of private hands, until it was acquired in 1921 by the Waltham Country Club. It established a golf course and tennis courts on the estate, but these initiatives failed during the Great Depression and the estate fell into disrepair. In 1935 the bank that took the property planned to sell off the estate for housing, but preservationists from the Society for the Preservation of New England Antiquities (now Historic New England), the Trustees of Reservations, and the National Society of the Colonial Dames of America in the Commonwealth of Massachusetts organized a drive to preserve the property. After a fundraising campaign the property was purchased by the Gore Place Society. The Society acquired of the original estate, and has rehabilitated its structures. About of the estate were leased to Raytheon, and are not open to the public. The rest of the estate is open to the public; house tours are offered for a fee.
