It retains its original acreage and original outbuildings, and its Spanish Baroque design was developed with Warren and Wetmore and Ronald H. Pearce. It is also tied to Vanderbilt, a railroad president, sportsman and marine collector.","narrative":"Eagle's Nest is a 43-acre waterfront estate on Little Neck Road in Centerport, overlooking Northport Harbor. William K. Vanderbilt Jr. began it in 1907 as a small summer house. Over the following decades it grew into a 24-room Spanish Baroque mansion with stucco walls, red tile roofs, a courtyard and a four-story bell tower. Warren and Wetmore and architect Ronald H. Pearce worked on its enlargement. The grounds hold reflecting pools, fountains, formal gardens and a golf course, along with original outbuildings: the Hall of Fishes museum, boat house, power house and garages, airplane hangar, caretaker's cottage, and former garage and servants' quarters. Only the 1971 planetarium is non-contributing. The estate is valued as a largely intact example of Long Island's Gold Coast estates, many of which were later subdivided. Vanderbilt used it as a retreat and as a museum for his marine collections, and it has remained a museum of marine life and natural history since his death in 1944.","period_of_significance":"1907-1936","architect_builder":"Warren and Wetmore; Ronald H.
