Lying barely 3 km (2 miles) from the mainland and 10 km (6 miles) from the nearest port (Pozzuoli), Procida is an island of enormous contrasts. It's the most densely populated island in Europe—just more than 10,000 people crammed into less than 3½ square km (2 square miles)—and yet there are oases like Marina Corricella and Vivara, which seem to have been bypassed by modern civilization. The inhabitants of the island—the Procidani—have an almost symbiotic relationship with the Mediterranean: many join the merchant navy, others either fish or ferry vacationers around local waters. And yet land traffic here is more intense than on any other island in the Bay of Naples.
In scenic terms this is the place to admire what the Italians call "Spontaneous," or folkloric Mediterranean, architecture: look for the tall archways on the ground floor, which signal places where boats could be stowed in winter, the outside staircases providing access to upper floors without cramping interior living space, and the delicate pastel colors of the facades contrasting with the deeper, bolder blues of the sea. Picturesquely scenic, it's no surprise that Procida has strong artistic traditions and is widely considered the painters' island par excellence.
