We start off facing a wall. Ahead of you to the left you will see an arch doorway. Go through the arch. Once you are through the arch, continue going straight down this hall. You will see some black rectangular shapes in this floorway. Continue walking and take a left going out of the front door. When you're looking outside you will see three archways. Go and stand in the middle of the middle archway and you will be at your destination. Actually, you will stop just before you get to the archways but you will still be in the middle one.
