Chооse the sentence thаt best expresses the implied mаin ideа оf the paragraph below. When Attila the Hun and his barbarian hordes swept across northern Italy in about 430 CE., they wrought havoc and destruction on the remnants of the Roman Empire. But they unintentionally left another, more positive legacy as well. Refugees fled burning cities, desperate to find safe refuge. Some literally took to the swamps, finding sanctuary in a desolate group of islands in a marshy lagoon off the northern Adriatic. When the Huns were followed by other invading tribes, more Roman citizens streamed to the swamps to avoid the carnage and destruction on the mainland. Over the next few centuries, they transformed the inhospitable surroundings into an architectural wonder: Venice. With more than four hundred bridges and almost two hundred canals, the city on the lagoon became a center of trade and a seafaring power. By the 1200s, Venice was the most prosperous city in all of Europe. Today it remains one of the most beautiful (and most visited) cities in the world.
