Ok, so on 56 (spoilers possible for those still on the riddle. Even if you think you know everything, you very likely do not.)
<So I've located all three instances of the wall. The only differences between the three walls that are immediately apparent are the words on the bricks, and the fact that one of them has the words "It is their creation..." printed beneath them. I'm fairly confident that I can deduce an answer from all of this, I think the trick is going to be where to actually type the answer. I'm thinking either back on #54, or on the wall with the "It is their creation..." printed.[/color]>
Anyways, headed home now, more work tomorrow.
