The giant stone arch to the colosseum looms overhead like a god, concealing shadows within its massive maw. High above are the second tier arches, which are mostly intact, and the fragmented remains of a third and fourth tier. Curving toward the nearest wall of the colosseum is a makeshift barricade, assembled obviously to create a single line of defense against some threat.
