Economic prosperity led to a revival in construction and urban development; temples and palaces were built throughout the country, as well as paved roads that linked the main cities like Baalbeck and Berytus. Indeed, starting in the last quarter of the 1st century BCE (reign of Augustus) and over a period of two centuries (reign of Philip the Arab), the Romans built a huge temple complex in Baalbek on a pre-existing tell dating to the PPNB,[1] consisting of three temples: Jupiter, Bacchus and Venus. On a nearby hill, they built a fourth temple dedicated to Mercury.
