In 140BC, the Phoenician city was destroyed by Diodotus Tryphon in his conflict with Antiochus VII Sidetes for the throne of the Hellenistic Seleucid monarchy. Laodicea in Phoenicia was built upon the same site on a more conventional Hellenistic plan. Present-day Beirut overlies this ancient one, and little archaeology was carried out until after the civil war 1991. The salvage excavations after 1993 have yielded new insights into the layout and history of this period of Beirut's history. Public architecture included several areas and buildings.
