Directly below where you entered the sewers, there’s a wooden scaffold with a sledgehammer leaning against the wall. Knock out the sleeping Blackshirt, then bust down the wall behind him to reveal a passage into a part of the sewer that isn’t on the map.
Follow the tunnel and duck under two half open gates. In the room on the other side, an artifact waits under the water.

Head back to the unconscious Blackshirt and then open the nearby gate with the Sewers Key.
Find the Palace Entrance
Follow the sewers until you reach a large round chamber with deep water at the bottom. Jump across the debris to the other side, then look for a pipe you can climb up on. Shimmy to the right until you can climb up, then continue to shimmy.
Near the end of the pipe it will break, and you’ll be able to climb out into the center of the room, where you’ll be in range for you to whip to a set of pipes hanging from the ceiling.
From there, swing from your whip until you can jump across to another set of pipes. Climb up to the top, then shimmy to the right where there’s a wooden platform. Whip to a second platform, then whip to the pipe just below the ceiling. Swing over to the last platform and climb up. While here, grab a photo of one of the inscriptions for Antonio.
