Oswald's Mansion requires cleanup to better fall in line with Amnesia Wiki's Manual of Style.
issue: not specified

Oswald's Mansion was the extensive home belonging to Oswald Mandus, built by his father in London and housing his family in the years before the events of 1899. It contains the first two areas (1st and 2nd) in the game.


The mansion is rather large, with spacious foyers and halls. It also features many rooms, most of which are inaccessible due to intricate locks.

Waking the Doll's House[]

Daddy, daddy!

Edwin and Enoch before Oswald awakens.

This is the first area of the game. This has Oswald Mandus' bedroom in it, where he wakes up at the start of the game to find his children. Besides his room, Lily's room can be found, as well as Edwin's and Enoch's room, and the attic that can be reached by pulling a rope in the ceiling. It is up here Mandus finds the first lantern. After picking up the lantern, follow the children until you see a large room with paintings on the wall. Descend the staircase to find the first phonograph.

The mansion also features a system of hidden passages and corridors which offer a view on the rooms through numerous paintings which turn out to be a sort of one-way looking glass. The first one of these can be found in Mandus' office, by using a hidden lever disguised as a rifle. Follow the hidden passage until you see a lever on the wall, pull it down to reveal a hidden door.

The bedrooms feature beds which are closed like cages: part of a mechanism for entrapping rich guests of the mansion and sending them to the machine, as detailed in this note: October 27th 1899.

Locks on doors and furniture throughout the mansion could be a safety measure against the Manpigs if some should wander into the mansion.

In Lily's Honour, a Banquet[]

I am off to market. I will cry all the way home. I will have none, I will have none at all.

This is the second area of the game. As you approach the staircase leading to the front door, you will hear a Manpig howling, though it is not encountered at all. Descend the stairs and you'll hear Mandus' children calling you, and then a small tremor which causes the chandeliers to swing a bit.

This part of the mansion is semi-integrated into the facility which is evidenced by numerous hidden sections leading to a number of machine rooms and also by the strong tremors caused by the Machine below. The machinery is hidden behind objects such as the Grizzly Bear at the trophy room, and the bathtub in the guest bathroom. The bear can be moved aside to open the hidden room, while the hidden room behind the bathtub can be opened by using a lever hidden behind a painting.

The mansion also sports a spacious courtyard which offers access to the streets and some parts of the machinery. This is the first part of the game where you have a chance to spot a Manpig, although the encounter is purely visual as it can not hurt you.

This area leads to the Cellar, which can be fully accessed once the machines are all turned on.


  • There are at least two shields, one depicting the exact same black eagle as those found on Brennenburg Castle shields. This implies that Mandus might have some sort of connection with the Order of the Black Eagle, just as Alexander had.
  • The caged beds are to trap guests who attend Mandus's parties, usually the rich. Once guests are drunk, drugged, and brought upstairs to their rooms, the cage springs and the bed tilts up to send them hurtling into the machine for sacrifice.
