The Temple of Jupiter, Baalbek

Baalbek is a town in the Bekaa Valley of Lebanon, situated east of the Litani River. It is famous for its exquisitely detailed yet monumentally scaled temple ruins of the Roman period, when Baalbek, then known as Heliopolis, was one of the largest sanctuaries in the Empire.
It is perhaps Lebanon's greatest Roman treasure, and it can be counted among the wonders of the ancient world, containing some of the largest and best preserved Roman ruins.
