The Time Warner Center consists of two 750 foot (230 m) twin towers bridged by a multi-story atrium containing upscale retail shops. The complex also contains office and residential tenants. Construction began in November 2000, following the demolition of the New York Coliseum, and a topping-out ceremony was held on February 27, 2003. The property had the highest-listed market value in New York City, $1. 1 billion, in 2006.
