So when I was playing through the last sequence of AC2 I found this...
At the last area in the game you can climb to the roof. From a certain ledge (by where the lever to open the door is) you can jump and grasp the ledge of a window and climb to the roof from there. Now time for infiltration. From certain places on the roof you can slip inside the building. Because I didn't pull the lever to open the door detection won't result in desynchronization, which contradicts the idea of having to be anonymous when in the building. However I'm unable to progress any farther in the game. Next I look inside the Sistine Chapel which is currently empty (it's empty until the last checkpoint before you kill Rodrigo). With more exploring I found climbable ledges outside the chapel that lead me to the secret passageway in the back of the church. There's also more to see in this area. There's a good view of the courtyard outside the chapel (the same courtyard you pass through when you exit the chapel in the beginning of AC:Brotherhood). There's also the place where the piece of Eden is hidden in Brotherhood.
