Ostia Antica is an archaeological park on the outskirts of Rome, where the streets and buildings of an ancient port city survive on a remarkable scale. Less ceremonial than the Roman Forum, it offers a vivid sense of everyday life: visitors can wander past apartment blocks, warehouses, shops, temples and public baths along the old stone roads.
Founded by at least the fourth century BC, Ostia grew into a busy gateway for goods arriving in Rome from across the Mediterranean. Merchants, sailors, officials and labourers lived and worked here, leaving traces that are still visible in the brickwork and mosaics. The port eventually declined, and layers of silt and sand helped protect much of the abandoned city.
Highlights include the theatre, the Baths of Neptune with their black-and-white marine mosaics, and the Square of the Corporations, where mosaics identified the offices of traders and shipowners. Look for the multistorey apartment buildings, or insulae, and a thermopolium with its ancient serving counter. With umbrella pines and long stretches of ruins to explore, Ostia Antica rewards a slower visit; allow at least three hours, or half a day if you can.
From central Rome, take the Metromare train from Porta San Paolo, beside Piramide metro station, to Ostia Antica, then walk across the footbridge to the entrance. Wear sturdy shoes and bring water and a hat, especially in summer, when exposed paths can be hot. Check current opening hours and last-entry times before travelling, as the park is typically closed on Mondays.
