Temple of Jupiter, Damascus
Damascus, Syria
The Temple of Jupiter in Damascus was built by the Romans, beginning during the rule of Augustus in the first century AD and with further works occurring at various times up until the rule of Constantius II. It was developed from an earlier temple on the same site that was dedicated to the god Hadad-Ramman and to its Greek equivalent, Zeus. It was later converted into a church in the 4th century and then into the present-day Umayyad Mosque in the 8th century.
