The statue is in the middle area where there are stone walls and metal grate/bars. It has a lit torch on the wall on either side of it, a big potted plant on each side of it, and a couple of small pots on the floor with flowers in them. The torches brightly illuminate the area. It's in the middle of the tunnels right next to where the tunnel starts south to the Citadel exit. "Use" talismen in order: west, east, south... Hope this is clear enough to help people.
