QUICK SUMMARY

Baalbek (ancient Heliopolis — "City of the Sun") is one of the most monumental archaeological sites in the ancient world, located in the Bekaa Valley of eastern Lebanon at the foot of the Anti-Lebanon mountain range. The site is renowned for two distinct phenomena: a complex of colossal Roman temples — the Temple of Jupiter Heliopolitanus (the largest Roman temple ever constructed), the remarkably well-preserved Temple of Bacchus, and the circular Temple of Venus — built between the 1st century BCE and 3rd century CE; and the enigmatic megalithic platform stones upon which the Jupiter temple sits, including the legendary Trilithon (three stones each weighing approximately 800 tonnes) and additional quarry stones — including the Stone of the Pregnant Woman (~1,000 tonnes) and a recently discovered quarry monolith of approximately 1,650 tonnes (the largest known hewn stone in antiquity). The transport and placement of these colossal stones has generated intense debate over whether Roman engineering alone is responsible or whether the platform incorporates elements from a pre-Roman Phoenician or earlier sanctuary. UNESCO World Heritage Site since 1984.
