HOW TO FIND A ROOM IN THE PENTAGON

Each floor's layout has five pentagonal concentric rings which are connected by ten spoke-like corridors.

Room numbers are comprised of the following information:

The first number or letter indicates the floor on which the room is located
(B = Basement, M = Mezzanine, 1-5 = floors).

The next letter is the ring on which the room is located.
(Rings are designated A,B,C,D, and E for the Mezzanine and floors 1-5 plus the
additional rings F and G in the basement only.)

The next digit or the next two digits indicates the corridor on which the room is located. (Corridors are designated 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10)

The last two digits indicate the specific bay or room number assigned to an office.

EXAMPLE, to locate room 3D126:

1. Go to the third floor, A ring
2. Proceed along the A Ring to the 1st corridor
3. Go down the 1st corridor to the Dring
4. Turn left and proceed to room or bay number 26

 

Typical floor plan of the Pentagon:

 

FLOOR
Proceed to floor by ramp, stair or escalator

RING
Take the main corridor (A Ring) to each numbered corridor.

CORRIDOR
Proceed along the numbered corridors
(1 thru 10) to a specific ring (B thru E)

BAY
Enter ring to the left for rooms/bays numbering below 50, and to the right for rooms/bays above 50.
