Yes.
“The corbeled arch is made of overlapping courses of stones, each block projecting slightly further over the opening than the block beneath. The weight of the blocks above the supported end of the the projecting blocks help prevent the unsupported ends from tipping and falling...”

True, though this dates from before 1700 BC, so the architectural flaws are understandable :)
