The Pokémon Mansion (Japanese: ポケモン屋敷 Pokémon Mansion) is an area located on the northern half of Route 212. It is a big, old mansion owned by Mr. Backlot, the owner of Amity Square. The house is well-guarded outside. It is also the home of the famous Trophy Garden, which is located to the rear.
In the games
The mansion has many rooms, the largest of which is Mr. Backlot's office, which appears to take most of the mansion's east wing. Mr. Backlot himself can be found in the office along with his butler, as well as a policeman who guards a statue in the room. The policeman prevents the player from touching the statue while he is on duty, but from 2 AM to 6 AM he is on break. In Pokémon Platinum, the player can also read a book lying on the desk to register Manaphy as seen in the Pokédex. This may be essential to completing the Sinnoh Pokédex.
The mansion's west wing contains other rooms with beds, where the player can rest themselves and their Pokémon. These rooms and the hallways are also filled with numerous maids. Doors at the end of each wing's hallway are blocked by a maid. Once per day in Pokémon Platinum, the player may approach the maid by the west wing's door to take the 5-Maid Knockout Exact-Turn Attack Challenge, in which five maids must be beaten in an exact number of turns, which is randomly determined each day and ranges from 5 to 9 turns. The prize for winning the challenge is a duel with either Lady Celeste or Rich Boy Liam.

In the anime
The Pokémon Mansion in the animeThe Pokémon Mansion was featured in Hungry for the Good Life!, with Mr. Backlot and his maid Monica living there. Monica first appeared before Ash and his friends trying to catch a Cleffa that had escaped from the mansion. Afterwards she took them back to the mansion to get out of a storm and meet Mr. Backlot. The group was then introduced to all the Pokémon living with Mr. Backlot and taken care by Monica, including a very gluttonous Swinub, which devoured almost all the Poffins Monica and Dawn had made for all the Pokémon present. After the group had thwarted Team Rocket's plan of stealing the Pokémon in the mansion, Dawn proceeded to catch the Swinub for her own. She also learned that the next Pokémon Contest was going to be held in Celestic Town.

The following morning, Mr. Backlot showed the three Trainers his Trophy Garden before welcoming yet another guest, Cynthia. Afterwards, Cynthia and the three Pokédex holders traveled together to Route 210.
