The ruins of Pompeii's main entrance is at Porta Marina, the most impressive of the seven gates that punctuated the ancient town walls. A busy passageway now, as it was then, it originally connected the town with the nearby harbour, hence the gateway's name. Immediately on the right as you enter the gate is the 1st-century-BC Tempio di Venere (Temple of Venus), formerly one of the town's most opulent temples.
