Tregaron Estate, formerly known as The Causeway, is a country house estate located in the Cleveland Park neighborhood of Northwest, Washington, D.C.. The Estate, built in 1912, was designed by architect Charles Adams Platt and landscape architect Ellen Biddle Shipman. The original owners Alice and James Parmelee, lived at the estate from its construction until 1940. From 1942 to 1958 it was occupied by Joseph E. Davies, who had served as the ambassador for the United States to Luxembourg, Belgium, and the Soviet Union and his second wife Post Cereal Company heiress Marjorie Merriweather Post. They renamed the estate Tregaron. Today the estate is occupied by a campus for the Washington International School and the Tregaron Conservancy.
