Three other contributing buildings survive: a barn, a greenhouse and a caretaker's house.","why_significant":"It is significant under Criterion B for its association with David Gelston Floyd, a shipping businessman, town supervisor and state legislator, and his descendants. Under Criterion C it is an outstanding and rare example of a mid-nineteenth century Italianate stone residence on eastern Long Island. It retains a high degree of integrity in design, materials and workmanship.","narrative":"Brecknock Hall is a two and one-half story Italianate mansion of square-cut ashlar stone in Stirling, northeast of Greenport on Long Island's North Fork. Shipping and whaling businessman David Gelston Floyd broke ground in 1851, and the house was finished in 1857 at an estimated cost of $30,000. Scottish masons did the stonework, and Italian craftsmen did much of the interior woodwork. Stone corbel brackets under the south and west windows are an unusual feature. The house had speaking tubes, indoor bathrooms, central heating and gas lighting. Stone buildings were rare in the area because of the lack of quarries. Floyd was a local bank officer and a state legislator, and four generations of his family lived here. Early twentieth century changes are attributed to architect Francis DeLancey Robinson. After years of changing ownership and vacancy, the hall remains highly intact. It sits on an estate that now includes a retirement community, with its barn, greenhouse and caretaker's cottage still standing.","period_of_significance":"1851-1954","architect_builder":"Francis DeLancey Robinson (early 20th century alterations)","architectural_style":"Italianate","criteria":["B","C"],"status_note":"The form states the hall had been vacant for several years but retains high integrity.
