Marina City is a mixed-use residential/commercial building complex that occupies an entire city block on State Street in Chicago, Illinois. It sits on the north bank of the Chicago River in downtown Chicago, directly across from the Loop district. The complex consists of two corncob-shaped, 587-foot (179 m), 65-story towers, which include five-story elevators and physical plant penthouses. It also includes a saddle-shaped auditorium building, and a mid-rise hotel building, all contained on a raised platform next to the Chicago River. Beneath the platform, at river level, is a small marina for pleasure craft, giving the structures their name. Designed by Bertrand Goldberg, Marina City was the first building in the United States to be constructed with tower cranes. == History == The Marina City complex was designed in 1959 by architect Bertrand Goldberg and completed in 1964 at a cost of $36 million, financed to a large extent by the union of building janitors and elevator operators, who sought to reverse the pattern of white flight from the city's downtown area. When finished, the two towers were both the tallest residential buildings and the tallest reinforced concrete structures in the world. The complex was built as a city within a city, featuring numerous on-site facilities including a theatre, gym, swimming pool, ice rink, bowling alley, several stores and restaurants, and, of course, a marina. Marina City was built in a joint venture with Brighton Construction Company, owner: Thomas J. Bowler, and James McHugh Construction Company. James McHugh Construction Co. subsequently built Water Tower Place in 1976 and Trump Tower in 2009, both also tallest reinforced concrete structures in the world at the time. Local Radio station WCFL operated out of Marina City in the office building of the complex. Local television station WFLD, (FOX Channel 32) had its studios and transmitter at Marina City for eighteen years until they were bought by Metromedia. WLS-TV (ABC Channel 7) kept its transmitter atop Marina City until the Willis Tower (formerly known as Sears Tower) was completed. Marina City was the first urban post-war high-rise residential complex in the United States and is widely credited with beginning the residential renaissance of American inner cities. Its model of mixed residential and office uses and high-rise towers with a base of parking has become a primary model for urban development in the United States and throughout the world, and has been widely copied throughout many cities internationally. Marina City construction employed the first tower crane used in the United States. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Marina City」の詳細全文を読む スポンサード リンク
