At Ostia Antica Archaeological Park, you’ll explore a remarkably well-preserved Roman town of stone-paved streets, mosaics, shops, and public buildings. Walk from Porta Romana toward the Forum area and see key highlights such as the Roman Theatre, the Baths of Neptune, and the Square of the Corporations with its black-and-white mosaic “logos.” You’ll also discover everyday spaces like insulae (apartment blocks), a thermopolium (ancient snack bar), mills, and large horrea (warehouses). Admission is included—simply redeem your ticket at the entrance and begin your visit (self-guided or with your private guide, depending on your selected option).
