Standing for decades as the hamlet’s best-kept secret, an old, secluded manor nestled within a sprawling stretch of property in Fort Salonga has come out of hiding — with a price tag of $6.45 million.

The Owl Hill estate, located at 99 Sunken Meadow Road, spans 27.63 acres and is the largest parcel of 1-acre residential-zoned land in Suffolk County. It is up for sale for the first time in more than six decades. It’s now the most expensive property in Fort Salonga.

The 6,500-square-foot home, whose construction began in 1897 and doors opened in 1903, sits surrounded by a serene haven of wooded forest and towering oak trees. The house has been occupied, and maintained, by the same Manhattan-based family for more than half a century as a summer and weekend residence. Maya Ryan, the current owner, who was unable to be reached for comment, recently decided it was time to pass the property onto another family or developer — according to Owl Hill’s listing agent Kelley
Taylor, of Douglas Elliman Real Estate.

Taylor said she’s lived around the corner from the property for more than 20 years and never heard of it until recently.

“That’s where the ‘hidden’ comes from in hidden gem,” Taylor said, calling the Owl Hills house one of a kind. “It’s pretty remarkable — like nothing you’d expect to see in Suffolk County or on Long Island. It’s never been developed on.”

The palatial estate, which the listing agent compared to Theodore Roosevelt’s Sagamore Hill home in Oyster Bay, is only 50 miles from New York City and contains more than 20 acres of completely untouched land. There hasn’t been a single renovation to the property since the 1940s when its
occupants expanded the kitchen.

The interior of the home speaks to the architectural elegance of a bygone era with original tiger oak and mahogany hardwood floors. There are five en suite master bedrooms and three staff bedrooms, with a soaring fireplace in each, as well as an expansive music/living room, a wood-paneled dining room and a massive basement. Outside, there’s a wrap-around porch and a two-car garage, all within what Taylor calls a magical forest.

As for potential buyers, she said she’s seen a majority of interest from developers, including one evaluating the property as the site of a 55 and better community. But, she said, the owner has preserved  3.75 acres of the property under New York State’s Transfer of Development Rights.

“A big family would certainly love the generousness of the estate, as would anyone who appreciates the particular beauties of well-made historic homes,” said Dawn Watson, public relations manager at Douglas Elliman Real Estate. “It’s quite extraordinary and the parklike property is expansive and lush.”

In March, the Town of Smithtown and the county raised a $1 million grant to be used to preserve a portion of the Owl Hill property for open space.

Smithtown scholar Corey Victoria Geske said although the property has been around so long, there still isn’t a lot of information in regards to its historical details.

“Owl Hill is another example of beautiful architecture in Smithtown for which the architect, to my knowledge, is as yet unknown,” Geske said. “This is the kind of house that deserves that kind of research attention because it’s so special with regards to interior detail and its location, built high on the hills of Fort Salonga.”
