Lying 31 kilometres southwest of Rome, Lido di Ostia this is Rome’s seafront. Most of the busy beach is privatised, so there is a surcharge for use and loungers and parasols. The jewel of the area is nearby Ostia Antica. The architectural site gives a fascinating insight into the everyday life of sailors, merchants and slaves dating to the fourth century B.C. It later became Ancient Rome’s port for 600 years.
