One of the most significant ports in all of Italy was Rome’s port at Ostia, now called Ostia antica. The port was on the Tiber and on the coast, though the growing problem with silt accumulation made it less than the best of ports. Anyway, Ostia was a big place … bigger in size than Pompei. By the end of the 1st Century AD, it had it all … including …
