…Heliopolis, a town in the Beqaa Valley of Lebanon situated east of the Litani River.
After Alexander the Great conquered the Near East in 334 BCE, the existing settlement at Baalbek had been renamed Heliopolis, from helios, Greek for sun, and polis, Greek for city.
Heliopolis (there is another Heliopolis in Egypt) becomes part of the territory of Berytus on the Phoenician coast in 15 BCE.
The city retains its religious function as a pilgrimage site to the sanctuary of the Heliopolitan Jupiter-Baal.
