Finally, the city gate. Porta Marina, "The Seaside Gate", was the entrance to the city from its harbour. This gate was a "service" entrance, more like a back door (as you can see, it's one-way only). The main gate was up north, on the Vesuvius side, and was called Porta Ercolano, "The Herculaneum Gate". It led to the nearby small town of Herculaneum, a seaside resort for rich Pompeiians (their Santa Barbara), which ultimately shared Pompeii's fate in the eruption.
