Start sneaking off to the North. Go against the wall and use the nearby narrow tables as cover as you go to the West. Slip back out the door you came in from. Turn to the North and use the inner courtyard to get some distance. You can just leave carefully using the Cherry Bomb on the large group of extremists that back the Western door out. Just throw them to the left of the group to get their attention over there.
You can also simply climb up and out of the area using the rooftops. From there you need to make it over the wall so find a place you can easily get to it and hop out. The Northern part of the abbey is very good for that. Finish this to complete the first memory.
