1300 N Astor St

"Designed and constructed around the same time as his Marina City complex, Astor Tower, one of Bertrand Goldberg’s lesser-known buildings offers prime real estate in the middle of the Gold Coast. Bertrand considered Astor Tower as a prototype for Marina City, as he would use the same internal concrete core structure method for both buildings. 24 floors with a concrete core that took 3 weeks to pour. The structure is emphasized, and the core is exposed at the ground and top levels. Astor Tower is remembered as the site where Beatlemania officially ended on August 11, 1966. The building was converted to apartments in 1979. "
