The three massive stones known as the Trilithon at Baalbek in Lebanon have long posed a difficult question for engineers and historians. Each of the three blocks weighs roughly 800 tons, heavier than a fully loaded Boeing 747, and they are set about six meters above the ground as part of the platform for the Temple of Jupiter. The standard explanation credits Roman engineers with using wooden cran…

Baalbek’s colossal stones have baffled engineers for centuries, yet new analysis just upended the leading explanation. The famed 1,000-ton blocks at the ancient temple site were long thought to have been dragged by massive Roman labor, but researchers now point to a detail that contradicts the entire theory.

The temple complex at Baalbek in Lebanon contains the largest stone blocks ever quarried in human history.
