Genoa is a city and a seaport in northern Italy, the capital of the Province of Genoa and of the region of Liguria. The city has a population of ca. 620,000 and the urban area has a population of ca. 890,000. Genua was a city of the ancient Ligurians. Its name is probably Ligurian, meaning "knee" (from Ancient Greek gony "knee"), i.e. "angle", from its geographical position, thus akin to the name of Geneva. Or it could derive from the Celtic root genu-, genawa (pl. genowe), meaning "mouth", i.e., estuary.
