Progress forward until you see a hole in the wall you can climb through, chest 28# is located to the left of this hole.


Go through the hole and continue on forwards.
Chest 29# is located in the corner of the room where you meet a lot of guards.


Chest 30# is hidden behind the stone wall right before you confront the merchant.

There are no chests in the area with the guards.
Continue navigating past the guards (past where you find your clothes in the uncensored version)
