About
About Tocra (Taucheira) – Cyrenaican Submerged Port
Mycenaean beaker find site refounded as Doric Taucheira ca. 620 BCE as grain export for Cyrene's chora; Town walls 3.2 km (5th c. BCE) enclose terraced acropolis with Apollo sanctuary and later Byzantine fortress (Justinian). Harbour's ashlar quays, slipways and breakwater now –0.5 to –4 m across 400 m reef front, sighted by Boardman–Hayes 1966 and mapped by underwater photogrammetry 2019 (Univ. Leicester Cyrenaica). Reactivated 10th c. Arab Tocra with Fatimid ribat; abandoned after Hafsid hill shift. Excellent reef preservation of Hellenistic grain silos and Early Christian basilica apse half in sea.
Why it mattersExemplar Hellenistic grain-port preservation linking Cyrene's agricultural surplus to Mediterranean markets; Mycenaean pre-layer proves early Aegean–Libya contact.
