Real estate mogul and art megacollector Aby Rosen won his battle in Manhattan to move Picasso’s “Le Tricorne” from his Seagram Building — but he’s still fighting in Old Westbury to erect a sculpture garden with a work by Damien Hirst that offends some locals.

Sources said the village’s full five-member planning board toured the grounds of Rosen’s A. Conger Goodyear House, which is on the National Register of Historic Places, on Friday to make its recommendations.

Rosen irked neighbors, as well as local mayor Fred Carillo, when he put a 33-foot Hirst sculpture, “The Virgin Mother,” on his property. It depicts a pregnant woman with her skin peeled off, revealing her skull, sinew and a fetus.

“Old Westbury is very uptight,” explained a source familiar with the area. “They don’t like anything that changes the tone or tenor of the primarily WASPy enclave. It’s a gossipy town and was sent into a tizzy over this sculpture.”

Local officials held a June hearing on the matter, but put off a decision until July so the planning board could tour the grounds, which Rosen bought in 2011 for $3.4 million. The mayor’s reportedly advocated instituting local height limits for “accessory structures” like Rosen’s artwork.

Meanwhile, the mogul reportedly submitted a site plan that included other large sculptures, including a giant “Hello Kitty” figure by Tom Sachs and a 1986 Keith Haring work.

A source said the board did the walk-through in order “to get a visual of what he’s proposing. Then they’ll make suggestions,” which could include “screening” the sculptures from the road with foliage, which Rosen has reportedly offered.

The source said Rosen would then make the suggested changes to his site plan to submit at a July 7 open hearing.

The New York Landmarks Conservancy had locked horns with Rosen when he wanted to move the Picasso from the Seagram Building, but recently agreed it’ll go to the New-York Historical Society.

A rep for Rosen had no comment.
