Harbor that supplied ancient Rome with wheat discovered via sedimentary cores. (via First harbor of ancient Rome rediscovered)
“Archaeologists have unearthed the great ancient monuments of Ostia, but the location of the harbour which supplied Rome with wheat remained to be discovered. Thanks to sedimentary cores, this ” lost ” harbour has eventually been located northwest of the city of Ostia, on the left bank of the mouth of the Tiber. Stratigraphy has revealed that at its foundation, between the 4th and 2nd century BC, the basin was deeper than 6.5 m, the depth of a seaport.”
