About
About Leptiminus (Lemta) – Submerged Harbour of Byzacena
Punic Leptis Minor founded 8th c. BCE as Tyrian/Phoenician grain and oil port for Carthage hinterland; under Rome, Civitas Liberalis and centre of Africa Byzacena's olive monoculture – Lepcitane amphorae factories (Torcular, kiln mounds) ring harbour. Roman imperial navalia quay at –1 to –3 m extends 240 m with bollard stones; thermal baths (Hadrianic) half under beach, mosaics at water's edge. 1990–2019 Michigan-INP Leptiminus Archaeological Project (L. Stirling, R. Wilson) mapped submerged causeway to Djerba island chain and Garum basins, ceramics quantify Annona shipments to Ostia. Abandoned after Vandal 439 and Arab 698 shifts.
Why it mattersQuantifies Roman African olive economy – kiln counts scale Annona oil shipments to Rome; only intact Punic–Roman Sahel harbour sequence.
