MAP47: The Citadel is the forty-seventh level of PlayStation and Sega Saturn versions of Doom, and the seventeenth level of the Doom II episode.

Map of The Citadel
Letters in italics refer to marked spots on the map. Sector numbers in boldface are secrets which count toward the end-of-level tally.


There are three keys but you do not have to collect them all. Opening blue and red bars (or yellow and red) will be enough to squeeze into space between them and finish the level.

In the starting area, enter the building in front of you. Knock off one or three shotgun guys. Enter the room to the right. In the room, push the skull switch. This will unlock the door to the citadel. Return to the first room and turn right. Open the door and cross the bridge. Enter the citadel.

Red key

In the citadel, go up any staircase and open the lion panel to the left. In the room push the skull switch to open two doors. You need to enter the northern door. You will be in a dark corridor. Turn right and open the lion panel. You cannot take the soulsphere yet. If you try to, you will teleported to another area (that you need now). In this area all you need to do is to shoot the cage to the left. This will raise a platform which will help you to get into the door (in case of you fall down before the platform is risen, you need to press the button on it while it is in the sunk level; use the automap to see the line in yellow; the first platform will lower and you will be able to raise the second one). Now, open the door and descend down until you can take the red skull key (taking the key also counts as secret). Fall down to the central area. Kill enemies here and collect items if you want. Take the door in the south to get back.

Blue key

Back in the entrance of the citadel, open the lion panel to the west. In the room push the skull switch to open two doors. Enter the northern door. In the dark corridor go forward until you can see an opening of the citadel to the outside. Do not jump there but instead open the wall to the left. There is an armor and it is counted as secret. Squeeze here and use a lift which brings you to another opening. Leap from here down to the water and to the red brick building. Ascend on the stairs and enter the entrance to the right. Beware of the slow crushing ceiling. Carefully enter the following room. In the room head into the wooden tower. Inside, push the skull to open two passageways. You need the passageway to the left. It will lead you to a dark room with five teleporters. You need the one to the far right (north east). Once you will be in a room, fight all the demons here and drop into a small shaft next to the skull button where you can take the blue skull key.

Yellow key

Get back to the room with five teleporters again (described above). This time, use the teleporter to the closest left (south west). In the room bump against the brick wall when climbing the stairs and it will lower. When you see an opening to the familiar room, turn left and take the yellow skull key.


Once you are ready to complete the level, head out of the citadel and head to the north side of the map. You will see a small brick building and a marble house inside. Go around this marble house and you will see three multicolor key bars. Open as much bars as you can and step on the water pool to finish.

Other points of interest[edit]


  1. As you gain access to the citadel, enter it. Ascend the stairs and go to the left (west) room. Push the switch to open two doors. Go to the north one, and you will be in a dark corridor. Turn left and open the lion panel to enter caged room. Destroy all imps and collect stimpacks and a partial invisibility sphere. (sector 40)
  2. Mandatory secret. Back in the dark corridor go forward to the north until you can see an outside opening to the left. A brick wall left of this opening can be pushed. Behind is an armor and a lift. At the top is secret#3. (sector 122)
  3. Mandatory secret. The lift in secret#2 will send you to the passageway which counts as secret. Both secret#2 and secret#3 are mandatory and cannot be missed, as you will use these passages at least once. (sector 124)
  4. Mandatory secret. From the passage of secret#3, leap to the water next to the red brick building. The first step leading to the building counts as secret and cannot be missed. (sector 110)
  5. Once you can reach the red brick building, ascend the stairs and take the south entrance. Push the skull to the right, and you will be able to enter a room. Enter it, destroy everyone and go back to the outside. A wall with numerous former humans will open, and you can obtain a computer area map. (sector 120)
  6. In the entrance of the citadel, ascend the stairs and open the lion panel to the right (east). Push the skull to build the stairs. Ascend the stairs and push the stone wall between two lions to the left (north). Ascend the stairs again and jump over the platform in the center and over the other platform where the teleporter is. The teleporter will lead you to the otherwise unreachable soulsphere. (sector 35)
  7. Finding the red key counts as secret on this level (see "Red key" section of the walkthrough). (sector 1)
  8. Finding the blue key counts as secret on this level (see "Blue key" section of the walkthrough). (sector 20)
  9. Finding the yellow key counts as secret on this level (see "Yellow key" section of the walkthrough). (sector 148)


  • One of four medikits (thing 338) in the central courtyard of the citadel has an improper arrangement resulting in suspending in the air.
  • When the room with a bunch of zombiemen is revealed in the red brick island area the players can see two distortedly displayed textures due to the wrong Y-offset setting.
  • The lift in the blue key area (sector 8; tag 25) has the same floor height as the key plat making that lift and the switch used to access it both redundant.
  • The teleporter destination (thing 105) in the south-west wing of the citadel is not set to work in the first two skill levels ("I'm too young to die" and "Hey, not too rough").
