Why it's listed
Eagle's Nest is a 43-acre waterfront estate in Centerport, on the Little Neck peninsula above Northport Harbor. William K. Vanderbilt Jr. began it in 1907 as a small summer house and later expanded it into a 24-room Spanish Baroque mansion with stucco walls, red tile roofs, a courtyard and a four-story bell tower. The architects were Warren and Wetmore, with Ronald H. Pearce also involved. The grounds hold the Hall of Fishes marine museum, a boat house, a power house and garages, an airplane hangar, a caretaker's cottage, reflecting pools, formal gardens and a golf course. Nearly all of these buildings are original to the estate. Only the 1971 planetarium is counted as non-contributing. The estate is considered significant because it survives largely intact with its original acreage and outbuildings, while many other Gold Coast estates were subdivided. It has operated as a museum of marine life and natural history since Vanderbilt's death in 1944.
Significance in brief: The estate is presented as one of Huntington's most intact early twentieth-century estates and a representative example of Long Island's "Gold Coast." It keeps its original acreage and outbuildings, and is a fine example of Spanish Baroque design. It is also tied to Vanderbilt's marine collections and to the architects Warren and Wetmore.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
