You will leave your hotel, the airport or the port of Civitavecchia to take a tour to Ostia. This town was the ancient, thriving port of Rome, which went into decline during the reign of Constantine and disappeared beneath the soil transported by the wind and river following the barbarian invasions.
Gregory IV founded the current town on its site in 827. Today, thanks to the archaeological excavations begun in the twentieth century, it is an important testimony of building, organisation and private and public life in a large Roman centre. Indeed, it is possible to visit the precious mosaics of the Baths of Neptune, the Theatre, the Temple of Rome and Augustus and the forum, with the ruins of the Capitolium, the town’s most important temple, dating back to the second century BC.
