Swan of a wealthy New York shipbuilding and mercantile family.","why_significant":"The house is described as one of the finest Second Empire style residences on Long Island. It reflects Oyster Bay's change from a rural farming and shellfishing settlement into a place of country seats for prosperous New York merchant families in the 1850s. It remains a typical example of the rural retreats central to the history of Oyster Bay and the North Shore.","narrative":"Edward H. Swan House is a brick residence on Cove Neck Road in Oyster Bay, built in 1853 and facing south over a formal lawn toward a meadow. Its double brick walls are separated by a nine-inch air space, and it rises two and one-half stories under a mansard roof of hexagonal slates. Round-arched windows, three-sided bay windows and a cast iron entrance portico mark the symmetrical front. A veranda runs along the west side, and a wing (1919) and belvedere (1920) were added later. Inside are paneled rooms, marble mantels and Corinthian columns in the dining room. A small board-and-batten cottage with scalloped bargeboards stands on the grounds. The house was built for a family that made its fortune in shipbuilding and maritime trade, after fire destroyed an earlier dwelling on the site. It is regarded as one of Long Island's finest Second Empire residences and as evidence of Oyster Bay's growth as a retreat for wealthy merchants.","period_of_significance":null,"architect_builder":null,"architectural_style":"Second Empire","criteria":[],"status_note":"Privately owned and occupied as a private residence; the form lists its condition as unaltered while noting a 1919 east wing and a 1920 belvedere.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:50:39.400406-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_NY/76001233.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/75319215","wikipedia":"https://en.wikipedia.org/wiki/Edward_H._Swan_House","wikidata":"https://www.wikidata.org/wiki/Q5343254"},"indexable":true,"url":"https://nationalhistoricalregister.com/new-york/nassau-county/swan-edward-h-house-76001233/"}
