The first proper harbour at Ostia was excavated under Claudius and finished in AD 64, and became the main trading centre for goods entering Rome from the western half of the Empire while Puteoli, on the Bay of Naples, continued to receive shipments from the east. However the harbour silted up over time, and so Trajan ordered the construction of a new basin, designed in hexagonal form and behind the original harbour, to offer better protection. Finished in AD 113, Trajan's new harbour at Ostia proved so popular that the the grain fleet from Alexandria in Egypt sailed to Ostia instead of Puteoli, and in the course of the second century Ostia became the main harbour of Rome for goods from the entire Empire.
