The “Interdimensional Museum of Backrooms History” (abbreviated as the I.M.B.H.) is the 217th level of The Backrooms and can be accessed easily through a specific door found in The Hub. The main concourse of this level is made up of four separate sections and three floors. Additionally, all the wings can be accessed in some way or another via the levels of the main concourse, and side stairways and elevators to the upper floor. Further directions can be found in directories or given by museum staff and guides.

Thanks to cooperation between groups such as The M.E.G., B.N.T.G., Eyes of Argos, Eternal Repository, and other groups1, we at the Museum of Backrooms History have been able to accumulate a vast collection of artifacts and exhibits donated at the behest of various peoples. Those who wish to access archives and resources pertaining to The Backrooms are permitted to do so within the halls of this facility. Security is guaranteed by the [MULTILATERAL PEACE AGREEMENT OF 1950] by multiple Groups who have made contributions to The I.M.B.H.

The Valentine Archives


One of many rooms within The Valentine Archives.

The secondary purpose of The Interdimensional Museum of Backrooms History is to store a catalog of records and other artifacts for public study and research. Many of the documents found within The Valentine Archives are donated by various major and minor groups within The Backrooms. This ranges from books to paper logs, digital works, audio cassettes, video recordings, physical items, and anything else donated which serves a historical purpose.

Access to The Valentine Archives is limited to those allowed access via a request to the museum staff and administrators; though in recent times due to tensions, access is harder to achieve. However, the archives can be accessed via multiple sets of locked doors or two code-locked elevators which access the lower levels where all of the archives are housed. A small yet highly trained security presence exists across The I.M.B.H., though staff and researchers mostly reside within this section of the level.

Down within the archives are multiple rooms, some climate controlled for the sake of preserving the specimens or items kept in them. Others are corridors upon corridors of drawers and cabinets for housing smaller artifacts and paperwork kept as historical references. Bigger artifacts are kept in specialty storage meant to accommodate larger items, featuring a special lift to transport them to whichever exhibit floor they are needed on at the time.

Digital, audio, and video records and artifacts that have been digitized can be accessed through a separate, secure server room featuring computers and PCs capable of processing data in safety. Records such as a copy of the M.E.G. database are kept for safekeeping within the I.M.B.H.’s Valentine Archives.


The Interdimensional Museum of Backrooms History can be found through the appropriately labeled double doors within The Hub. Entering them should harmlessly transport wanderers to Level 216 without any issue. To leave, one must simply leave through the same doors they entered. Doing so will either transport wanderers to Level 57, Level 164, and Mr. Castellos's very own Level 222.


Q. Which major group controls Level 216?

No one! We museum staff are an independent group of researchers who function for the betterment of human understanding of The Backrooms.

Q. What if I want to make a donation?

If you or someone you know wishes to make a donation, please contact our staff at moc.liamsmoorkcab|ude.HfoMB#moc.liamsmoorkcab|ude.HfoMB.

Q. How can I apply to work at The I.M.B.H.?

Simply contact staff in person or at the email above and we will then contact you back with further information.

Q. Are tours in other languages, or for the impaired offered?

Yes, some of us museum staff are multilingual or can hire translators, interpreters, or visual aids for tours upon visitor request, or with reservations.
