On this page of our guide to Uncharted 2: Among Thieves you will find a detailed description of secrets and collectibles available in Chapter 22 - The Monastery. Our step-by-step walkthrough explains how to find all (8) secrets hidden in the 22nd chapter of the main campaign.
The first secret is almost at the very beginning of this chapter. After climbing the rocks and defeating the first few enemies, bypass the parked cars and approach the big gate. A treasure is attached to the gate. Shoot at it so it may fall to the ground.
The second treasure is located near the area where the second battle with the enemies will take place, in the vicinity of the first buildings. Approach the edge of the cliff and look down. You'll see a red board below. Jump down near the board and collect the treasure.
The third secret is located near the only machine gun turret that is available in this chapter. You'll encounter it shortly after you collect the second treasure. The valuable item is hidden at the other side of the wall fragment (to the right of the aforementioned weapon).
After climbing a rope hanging from the yellow wall (Elena will drop it for you), you have to follow your partner. At some point, you'll have to jump over the river. The treasure is hidden right there, on the other side of the ruined bridge (you will have to go down to get it).
As you climb up the tower, you'll come across a greenish canopy (Elena will ask you to open the door from the other side and remain stealth). Jump on it and hang on to its edge. The treasure is right below the canopy. To get it, shoot at it with a gun and pick it up from the platform below.
The sixth secret is on the wall of the next tower, which you will reach shortly after you are attacked by an enemy with a rocket launcher. During the explosion the passageway for Elena will finally open. While being in the aforementioned tower, one of the ground floor corners will be destroyed. That's where you have to go - descend bricks towards the water. The item is lying next to the water.
The seventh treasure is relatively close to the sixth one, but it can only be collected after you've wiped out all snipers (while standing on top of the building). When you're on the ground floor, look around, and on one side you'll see a distant, partially destroyed bridge. It may seem that you won't be able to reach it, but actually - yes, you can. Run-up and make a last-minute jump as if you wanted to take off and fly. Once you land there, descend two ladder and look around. The treasure will be mounted on the wall, just before the cliff. Shoot at it so it may fall to the ground.
The last treasure can be found just before the end of the chapter. After entering a ruined monastery through the window (you have to walk on the beams beforehand), head to the opposite wall. There will be a window with bars. A treasure is attached to it. Knock it over and collect it - to get there you have to jump on the destroyed furniture and damaged walls of the building.
