Location and Protection
It is located at 1000 Mammon Avenue, on the corner of Croesus and Mammon streets in the Springfield Heights district. It is protected by a high wall at least 20 feet tall, an electrified fence, and a pack of 10 vicious attack dogs known as "The Hounds" one of which is named Winston. In addition, he has at least one 16+-year-old dog named Crippler. Crippler is known for bagging hippies - "something they don't find too groovy at all". At times he has employed for protection a force of Wizard of Oz - style guards, a personal paramilitary force, a riot police squad, and a robotic Richard Simmons.
The inside of the mansion includes a room containing a thousand monkeys at a thousand typewriters, a bottomless pit, a human chess board, the largest television in the free world, a 'Hall of Patriots' commemorating his ancestors, a laboratory, a botanical garden of vultures bearing his likeness, a safe containing a Beefeater guard, Lillie Langtry Theater, a theater showing round-the-clock plays regardless of whether there is an audience, and an illegal Surveillance Room for such a large mansion, it has a surprisingly small basement, seemingly no larger than the basement in the Simpsons home.
The mansion is also home to many rare historical artifacts including the only existing nude photo of Mark Twain, the suit Charlie Chaplin was buried in, King Arthur's mythical sword Excalibur, and a rare first draft of the Constitution with the word "suckers" in it.
He also has a large wine cellar with an entrance through the back of the mansion, the stairway has heads of a Dodo, Saber-toothed Tiger, Tyrannosaurus Rex, all of which are extinct, and a skeleton of a trespasser hung up on the wall. The wine cellar itself has hundreds of wine bottles, including a massive 60,000 dollar bottle of wine which Homer drank.
He also has a room filled with priceless paintings, including The Concert by Vermeer which was stolen in March 1990. It is considered the most valuable painting ever stolen with an estimated value of 200 million dollars. Chief Wiggum and Lou arrested Burns for the burglary and most likely confiscated the painting.
Burns Manor has 137 rooms and at least 3 floors visible from the exterior (not including the basement or attic).
In The Simpsons: Hit and Run, the mansion's size is exaggerated and out of proportion, with the only room accessible is Mr. Burns' office only in Level 4. However, in both Level 1 and 4, the back of the mansion can be accessed through the Power Plant via a hidden tunnel above a pipe-bracing. The back of the mansion sports the aforementioned human chess board, only the chess pieces act as the typical destructible/damageable objects that can be knocked over to fill the Hit & Run meter and earn coins.
