Head back to the district's western wall and follow it south until you descend a big staircase into the map area pictured below. Climb up on the nearest roof, and you'll find the next Fragment on this ledge:
After grabbing Fragment 1, turn and look southeast until you see this building, with the three big archways. The next Fragment's sitting on the middle one.
Look northeast from Fragment 2, and you'll see a mosque-looking building next to a Viewpoint. Fragment 3 is floating above its highest dome.
Southeast of Fragment 3's location, you'll find the next Fragment suspended on a clothesline over a courtyard that's home to a group of Romanies.
Due east of a bookshop and just south of a medical shop, you'll find the next Fragment on the dome of yet another mosque-looking building.
This Fragment's relatively easy to find, seeing as it's at the top of the tower of Constantine South's Assassin Den.
The next Fragment is visible from street level, and sits in an alley just northeast of a bank.
Head back toward the western wall. A short distance south of the Romani headquarters and northwest of the Arcadius tunnel entrance, you'll find the next Fragment in the corner of a recessed courtyard.
A block or two southwest of Fragment 8, you'll see the next Fragment on an outcropping sticking out of the western wall.
To get there, climb up to the roofs opposite the Fragment and use the hookblade to swing across on that dangling plant hanger, or whatever it is.
Head southeast from the last Fragment, and you'll see the next one in the middle of a walled graveyard, on the slightly raised, column-ringed platform shown below:
From Fragment 10, head south and slightly east to the southwestern corner of the city. Here, you'll find Constantine South's final Fragment on top of a pillar near the southern wall.
