There's a memory fragment on a wooden platform sticking out of the side of Galata Tower:
How the heck do I get to it?
As far as I can tell, there is no route to climb up to or around it (unless I'm missing something obvious). I tried climbing above it and dropping down onto it, but when I let go of the wall above I plummet into a hay pile below instead of down to the platform (which is actually good since in order to get above the platform you have to get high enough that the fall would probably desynchronize you).
So how do I get this darn thing?
