Any idea where/what it is?I've seen that one too. Very cool.
Absolutely not. They obviously won't slide at all. You have to place alternate beams.I'm trying to understand how one would put those together. You can't slide one end into the other, can you?
i would have swore it was top downThey have to be stacked from the bottom up.

I believe they all serve to enhance the structural integrity but the 2nd one is slightly redundant, yes.So is the second "hook" tenon (do those qualify as tenons?) purely aesthetic or does it actually serve from a structural perspective? I would assume any added strength or stability would be negligible but it sure looks awesome. I bet that thing could survive another 500 years.
