MarinaBlue, also known as Marina Blue, is a skyscraper in the City of Miami, Florida, United States. It is located in northeastern Downtown, and forms part of the Biscayne Wall, a series of skyscrapers visible from Biscayne Bay along the west side of Biscayne Boulevard. The tower was one of the first buildings making up the wall to be completed. Built by Hyperion Development, the developers of another building named Blue on the Bay further uptown, the building finished construction in May 2007. Marinablue is located across the street from the American Airlines Arena. The building rises 615 feet (187 m), and contains 57 floors. Marinablue is almost all-residential, with some retail and office space on the lower floors. The building was opened to residential occupancy since the spring of 2008. The building currently stands as the 9th-tallest in Miami and the 10th-tallest in Florida, as well the 5th-tallest residential building in the city and the state.
