From Newsday 5-5-2025:
The primary shooting locale of the Netflix miniseries “Sirens,” streaming May 22, was the grounds of the Caumsett State Historic Park Preserve, on the Lloyd Neck peninsula jutting out into Long Island Sound.
“The script of the show fits in with how Caumsett is structured,” explains Park Director Vincent Medina of the dark comedy taking place over the course of a weekend at the “beautiful giant property with multiple buildings on it” belonging to an eerie socialite philanthropist (Julianne Moore) and her billionaire husband (Kevin Bacon).
The 1,750-acre Caumsett contains historic buildings including the Henry Lloyd Manor, built in 1711, as well as the 1920s Dairy Barn Complex and redbrick Polo Stable, the 1939 Summer Cottage and other buildings once belonging to investment banker and department-store heir Marshall Field III. New York State acquired the property in 1961.
A filming permit was approved in June 2024, Medina says, and the production, also starring Meghann Fahy, Milly Alcock, Glenn Howerton and Josh Segarra, filmed at the park for 10 days throughout July, August and September. Scenes from the miniseries were also shot in Southold, in July 2024, at a private property on Oregon Road in the town’s hamlet of Cutchogue.
While the production shot mostly exterior scenes at Caumsett, “They also had a set in the old main office here,” Medina says. “They turned it into a jail cell, like in a precinct.”
Additionally, “They built a small set down by the bath house,” he says, referring to an area informally known by that name where a since demolished, cedar-shingled Cape Cod bath house once stood near a pool and red-clay tennis courts. “They called it an aviary, so I guess within the show it has something to do with birds.”
The miniseries’ trailer shows Moore releasing some bird of prey at the edge of a cliff — one not actually there. “They CGI’d the front of that bluff,” Medina says, referring to computer-generated imagery.
