City’s spooky spots have become real estate hotspots

Home, strange home.

Developers are making over shuttered opera houses, TB wards, asylums and poorhouses in the hope of luring new life to the city’s oldest haunts.

Meanwhile, abandoned hospitals are being converted into condos — including the boxy St. John’s Episcopal Hospital in Queens and Cabrini Medical Center in Gramercy.

Real-estate bigwigs are also vying for Brooklyn’s Long Island College Hospital.

“Some people [would rather] live in the psych ward with high ceilings as opposed to cookie-cutter buildings,” said developer Don Peebles. “It’s a reminder of the history of New York.”

Here are some of the city’s creepy sites in search of new souls.

Farm Colony, Staten Island

Abandoned for decades, this decrepit 19th Century “poor farm” is slated to become a residential community for seniors.

Its majestic brick buildings on 90 acres housed thousands of indigent people who grew vegetables to earn their keep. It later became a geriatric hospital before being closed in 1975 and left to rot.

Sea View Hospital Rehabilitation Center & Home — a brain-injury center on the site of the old Sea View Hospital, which was built in 1913 as one of America’s leading tuberculosis hospitals — is across the street. Some of its deserted buildings (the site was landmarked in 1985) are also being turned into senior housing.

“It always reminds me of ‘Poltergeist,’ ” said Joshua Zeman, a Staten Island native who directed “Cropsey,” a documentary about the urban legend of an escapee from Willowbrook State School, a shuttered mental institution, that segues into the true story of Andre Rand, the borough’s infamous convicted child kidnapper.

“You move the headstones, but you don’t move the bodies,” Zeman added. “That’s Staten Island — all of this development on top of somewhat nefarious historical places.”

Amato Opera, Manhattan

The Bowery’s opera house is being turned into apartments with a retail tenant on the ground floor. Built in 1889, the shabby four-story building was a theater run by Anthony Amato until it closed in 2009. Some preservationists say it’s haunted.

“There was definitely a sense of sorrow in the building,” said Allison Siegel, who chronicled her trip inside the decrepit building on the local blog Bowery Boogie.

“When I was there, I heard a piano playing,” Siegel told The Post. “Something wanted me to know it was there — that the opera house is going to continue to play on.”

Greenpoint Hospital, Brooklyn

Greenpoint Hospital Nurses Quarters, Brooklyn, NY.Angel Chevrestt

A nurses’ residence at Greenpoint Hospital, built in 1914 and abandoned since 1982, is being eyed for affordable housing.

The hospital — which is now affordable housing itself — took in famed whistleblower cop Frank Serpico after he was shot in the face in 1971.

In 2012, a developer who won a contract for the nurses’ quarters backed out over bribery charges. Now community developer St. Nicks Alliance is fighting the city to rehab it.

Mary Immaculate Hospital, Queens

Founded in 1902 by Roman Catholic nuns, the Jamaica hospital started as a 10-bed house before expanding its campus to include 162 beds. The property — now owned by developer Joseph Chetrit, which plans to turn it into market-rate apartments — has been a trash- and graffiti-filled eyesore since shutting down in 2009.
