Green Goblin's Mansion

The Green Goblin's Mansion is a large manor owned by the Osborn family, specifically Norman Osborn, the founder and genius behind OsCorp.

With his high intelligence, Osborn experimented with a green, super-power giving serum, but after a freak accident in his personal laboratory, the serum made him both physically and mentally peaked. However, it twisted his mind, morphing him into a cackling psychopath bent on spreading chaos and the death of his heroic nemesis, Spider-Man. As such, the mansion became the storage grounds of the Goblin's equipment such as his iconic suit of armor, his hovering "surfboard", and his army of lethal explosives.

It is also where he resided and was eventually taken over by his son, Harry, after Norman's death by his own, accidental hands. With Harry inheriting both OsCorp and the manor, he became the New Goblin, storing his original weaponry in the very same laboratory his deceased, sociopathic father did, and sought revenge on Spider-Man, who was framed for Norman's death. The mansion was later destroyed in Spider-Man 3.
