Climb the ladder and make your way up the steps ahead. The large clearing is patrolled by three undead, with a fourth playing dead near one of the exits. Head through the corridor and down the stairs, clearing out the enemies.

Get to the top of the ladder, turn around and face the ladder and kill the bad guys as they come up the ladder after you. Contunue on, climbing and killing off archers. Advance along the scaffold until two hollow knights meet you along this stretch.
