According to experts in esotericism, Villa Manzoni is one one the 9 doors to Hell, abandoned for long time until the intervention of the authorities. Black masses were organised inside the villa and the animals sacrificed during the rituals were then hanged outside the gate. The villa is also connected to Veio Necropolis through undergound galleries and people say that strange presences live around the area. All these stories are probably the reasons why the villa was abandoned long time ago.
