its condemnation in 1992, the stadium has become a haven for graffiti artists, but remains an attraction for its photographic panoramic view of the central business districts and barrier islands of Miami. Design Poured entirely in concrete, the Miami Marine Stadium consists of a dramatically cantilevered folded plate roof supported by eight big slanted columns anchored in the ground through the grandstand. A huge horizontal beam tied them all together. A cut in the seating arrangement allowed spectators to appreciate the full height of the posts, which were pushed as far back as possible to permit unobstructed views over the watercourse. This concept was presented by one of the project's architects, Hilaro Candela to be original, however the idea was synonymous to several other well-established stadiums throughout Latin America and Europe, including the Florence Stadium designed by Pier Luigi Nervi, built 1932, the Baseball and Soccer stadiums in Cartagena, Colombia, by Guillermo Gonzalez Zuleta in 1947 and The University Stadium in Caracas designed by Carlos Raul Villanueva, built in 1950. The Miami Marine Stadium bears striking resemblance to the more elegant horse-racing Hipódromo de la Zarzuela in Madrid, Spain, designed by Carlos Arniches Moltó and Martín Domínguez in 1934-1935. Revitalization On April 28, 2009 the National Trust for Historic Preservation named the Commodore Ralph Middleton Munroe Marine Stadium to its list of America's 11 Most Endangered Historic Places and as a National Treasure in March 2012. On April 18, 2012, the Florida Chapter of the American Institute of Architects placed the stadium on its list of Florida Architecture: 100 Years. 100 Places as the Ralph Middleton Munroe Miami Marine Stadium. A group, Friends of Miami Marine Stadium, was formed in 2008 with the purpose of restoring the Marine Stadium and returning it to operation. Performer Gloria Estefan, through her charity group, is a major contributor to Friends of Miami Marine Stadium. The City of Miami granted control of the stadium property to the group in 2013, and the group returned in late 2014 with a revitalization proposal and supposed funds. This project has brought the Miami Boat Show to the Miami Marine Stadium, and the show will take place February 11–15, 2016. In the past few years the site has been used for special events, such as The Miami International Boat Show and the 2019 USA Swimming Open Water National Championships. In 2016, the Miami City Commission voted to approve
