Aventura has seen its economic base grow dramatically in the past few years - a prime reason for many new businesses arriving in the area. The business center in the Corporate Center consists of two five-story buildings set in landscaped grounds and is centrally located in the heart of Aventura within walking distance of the Gulfstream Complex. The building mixes steel, and glass with concrete panels. Attached to each building is a two-story parking garage. Nearby Miami is a major US center of commerce, finance and international business, with several international companies headquartered in or around the city. It boasts the largest concentration of international banks in the US and, because of its location, Miami serves as the Latin American headquarters for more than 1,400 multinational corporations including Microsoft. Tourism, of course, is a major industry and the Port of Miami is known as the Cruise Capital of the World.
