Buenos Aires is one of the largest cities In Latin America. Also it ranks as the leading financial, industrial, commercial, and cultural hub of the region. The port of Buenos Aires has historical importance. So the people of the Buenos Aires city are called as portenos (people of the port). Today, this port is one of the busiest ports in South America.
