Arrange the 5 switches to match the inscription over the door to the left of the entrance: Up, Up, Down, Down, Up (Ω Ω Υ Υ Ω).
Drop down and go through that door.
Go round the tall, square pillar in the center of the room and through the doorway at the back.
Turn right and go down the stairs to the small room at the bottom.
Pull the movable block once to cause the ceiling to collapse in the room above.
Return up the stairs.
Continue straight ahead up several more flights of stairs...
...to an opening overlooking the now sand-filled room.
Take a standing jump from the doorway to the flat ledge below and to the right. It's easy to overshoot, so aim for the right side of this two-tile area, or press Action as you jump to shorten the distance Lara travels.
Take a running jump from the left side of the flat ledge to grab the right (lower) side of the broken pillar. Pull up.
Then take another running jump along the right side of the broken pillar to grab the left (higher) end of the angled ledge just to the right of the elevated doorway. Pull up again.
Finally, take a standing jump into the doorway.
If you miss any of these jumps and slide to the floor, just return through the doorway on the west side, turn left, and climb the stairs to get back to the doorway overlooking the sand pile.
DARK MODE: Even with brightness adjusted, dark images on a light background can be hard to see. May I suggest a reputable dark mode browser extension, such as Dark Reader? (Download only from trusted sites, like darkreader.org or your browser's web store.)
