The interior of SCP-3790 consists of several descending levels, each consisting of a hallway containing four doors, two per side, and a grated freight elevator at the far end of the corridor leading to the lower levels. While there is evidence of prior human activity within SCP-3790, the structure appears to have been abandoned for a considerable amount of time.

Each of the doors is a solid, heavy metal door with a sliding panel covering a small glass viewport into the dimly lit chamber beyond. The doors, some of which are rusted but otherwise undamaged, have at some point in the past had their handles and unlocking mechanisms removed, and have been welded shut. The only distinguishing marks on these doors are small metal placards located just beneath the sliding panel. These placards usually bear what is believed to be the designation for the contents of the chamber, though in some cases the placards have been removed or are damaged.

A clipboard holding a legal pad hangs on the back of the main access door. Several pages appear to have been torn away from the pad. The frontmost intact piece of paper contains a list of names and a short note. The remainder of the pages are irrelevant.

The elevator has access to seven levels of the structure.

No record of the SCP Foundation ever having a Department of Abnormalities exists. No information regarding the structure has been located.

Addendum 3790.1: Chamber Contents

The following is a list of the rooms on each floor, the text on each door's placard, and a visual description of the contents of each chamber, if possible.

Level One

Room One

Placard Name: Vivaldi

Description: Chamber is empty aside from a violin propped in the far corner of the room. The bow is broken on the ground in front of it.

Room Two

Placard Name: Montezuma's Face

Description: An ornate wooden chest with gold inlays and a large steel lock sits on a table in the middle of the chamber. A quiet clicking sound, like that of a clock, is barely audible from within the chamber.

Room Three

Placard Name: The Watchers

Description: Three vaguely humanoid figures are huddled in a far corner of the room, looking away from the door. The figures can be seen shifting slightly, but due to lighting conditions within the chamber, no other details can be made out.

Description: Beyond the door appears to be another dark hallway.

Description: The floor of the chamber is covered with a thin layer of water. The interior of the room seems to be considerably larger than its exterior physical dimensions would allow.

Placard Name: Adam's Hatred

Description: A billowing, indistinct black shape is visible in the back of the room.

Room Two

Placard Name: Wormwood

Description: Viewport is obscured.

Room Three

Placard Name: Harmonia's Necklace

Description: A simple golden necklace hangs on a post in the back of the room, which is lit by a single tall candle. The chamber does not appear to have a floor.

Room Four

Placard Name: No placard

Description: Chamber is unlit. Individuals who look into this room feel a lingering sense of dread afterward.

Level Five

Room One

Placard Name: The Heart of Man

Description: Inside the chamber is a single, still-beating human heart suspended from the ceiling by a wire. The interior of the chamber appears distorted.

Description: A wooden chair sits in the far corner of the room. A faint shadow can be seen 'sitting' in it, which disappears upon a second viewing.

Room Three

Placard Name: Ötzi

Description: A layer of ice covers the viewport and obscures visibility. A dark shape can be seen in the middle of the room, although no details can be distinguished.

Room Four

Placard Name: Apollyon's Crown

Description: A silver lockbox rests on a table in the middle of the room. Notably, the exterior of the door is covered in scratch marks, as if by something trying to get into the chamber.

Level Seven

Although the opening to the seventh level is visible through the grated floor of the elevator, the lift mechanism appears to have been modified and can no longer access that floor.
