About
About Sybaris — Trapezoid Trench Buried Second City (Sybaris–Thurii–Copia)
Second trapezoid trench sector of Sybaris, where Achaean Sybaris (720–510 BCE) lies 4–6 m buried under Thurii (444 BCE) and Roman Copia (193 BCE) alluvium on Crati delta. First trench 1960s Rainey-LeRoy under Parco archeologico di Sibari exposed Sybarite stoa and port facilities; second trapezoid sector now re-excavated 2020s CNR boreholes reveals preserved archaic street, harbour quay and Copia theatre under 6 m Barnett sands. City sacked by Croton 510 BCE and deliberately diverted Crati over ruins. Distinct from main Sybaris Park entry by isolating western trapezoid buried port quay study trenched 2023.
Why it mattersOnly stacked triple polis in Magna Graecia — 6 m stratigraphy tests historical Crati diversion legend; harbour quay solves Sybaris port puzzle that eluded 50 years.

Mysteries & theories
Mysteries
- 01Whether Crati diversion is myth or borehole proves river engineering
- 02Harbour location vs now 5 km inland delta
Theories
- 01Crati was indeed diverted — Barnett sand horizon 510 BCE
- 02Port quay proves Sybaris was lagoonal harbour not open-coast
Theories are interpretations, not findings. The seal above tells you how much scholarly weight the place carries.
