NY mob boss John Gotti's mansion sits abandoned in Old Westbury with many possessions still inside. The Gotti compound boasts a main house, a pool/guest house, a garage, a horse stable with an unfinished in-law apartment, an overgrown basketball court, and a triple-level hot tub/pool/swim-up bar. This was the mansion that Gotti's daughter Victoria called home with her 3 sons John, Carmine, and Frank. They filmed the reality show "Growing Up Gotti" here for 3 seasons in 2004 and 2005. After the feds raided the mansion in 2016, it has laid dormant with a lot of possessions left behind. What trespassers found was something no one expected. A hidden room behind a built-in bookshelf.
