Vlad Masters' Mansion is a residential location from the original show.
The first and most well-known mansion established in the series is the luxurious, expensive home of Vlad Masters in Madison, Wisconsin. It contains a secret lab with Vlad's own ghost portal and ghost-related gadgets. In "Eye for an Eye," this mansion was destroyed by the Guys in White after having previously been rebuilt from an explosion that occurred in "The Million Dollar Ghost." After the second loss of this mansion, Vlad moved into the Mayor's Mansion in Amity Park.
