What do Marseilles and Genoa have in common?

Marseilles and Genoa share a significant historical and geographical feature as important ports on the Mediterranean Sea. Both cities have played crucial roles in maritime trade and commerce for centuries, benefitting from their strategic locations along this vital waterway. Marseilles, located in France, and Genoa, in Italy, are known for their bustling harbors, facilitating trade routes that have historically connected various cultures and economies across the Mediterranean region. Their status as ports has contributed not only to their economic development but also to their cultural exchanges and interactions with other maritime nations over the years.

The other choices do not apply: neither city is a national capital, they do not share a border with Germany, and while Marseilles is in France, Genoa is in Italy, so they do not both lie in the south of France.
