The Treacherous Mansion is a location in Luigi's Mansion: Dark Moon and Luigi's Mansion 2 HD. It the final mansion visited by Luigi. The Treacherous Mansion is a large museum and is also the location of the final Dark Moon piece. Many rooms on the first floor of the Treacherous Mansion are based on the previous mansions in the game. Almost every ghost that Luigi encounters appears here, though most of them are stronger. King Boo comes to this mansion to open a paranormal portal to unleash almost every ghost that Luigi has ever encountered, such as Greenies, Slammers, a Gobber, Sneakers, mummies, Hiders, and Creepers, and most of these ghosts are either shielded, strong, or equipped with a weapon of some form. This multitude of ghosts will bring about the destruction of Evershade Valley. There are also gargoyles inside and outside the mansion.

The Treacherous Mansion is the only mansion in the game that requires Luigi to unlock just one door; the rest of the doors are already unlocked. It is also the only mansion besides the Gloomy Manor and Old Clockworks that has multiple music tracks; the track changes whenever Luigi looks through a window or crack in the wall. It is also the only mansion to have two missions primarily dealing with ghost-capturing: Paranormal Chaos and Terrifying Invasion. It is also the only mansion to have multiple false doors. Finally, it is the only mansion whose respective Dark Moon piece and Possessor ghost are not found in the mansion's vicinity.

The bottom four exhibits in the mansion are based on the four previous mansions in the game in some way. The Dark Age Exhibit represents the Gloomy Manor due to the knights found in the manor (despite not having the same music tracks), the Jungle Exhibit represents the Haunted Towers due to both having botanical designs, the Ancient Exhibit represents the Old Clockworks due to the latter having an Ancient Egyptian-like basement, and the Ice Age Exhibit represents the Secret Mine for their icy themes.

The Treacherous Mansion is an abandoned museum positioned right in the middle of a giant ravine, which becomes cut off from land access after Luigi reaches the front steps. According to E. Gadd, the mansion contains artifacts and items from Evershade Valley and beyond, making it the most "precious" of the mansions. The mansion is slightly changed to a spookier feel after King Boo arrives. It is called the Treacherous Mansion likely because it could collapse into the ravine below. It, however, does not at any point.

Trivia

• This is the only mansion where Luigi has to rescue two Toads in one mission.
• While Luigi is under the mansion in the Dungeon Cells, Professor E. Gadd will call him, but with no interference with the Dual Scream.
• The Treacherous Mansion is likely based on William Hope Hodgson's 1908 novel The House on the Borderland, in which the denizens of the titular house are assaulted by creatures from another dimension. Similarly, the house in the novel gets a large portion of the ground below it spirited away, leaving the house stranded on a ledge directly above a large water-filled ravine.
