Omaha architecture has grown from false-front buildings along the Missouri River to modern skyscrapers.  The CIty of Omaha does have a program for designating local historic/architectural landmarks.

Some of Omaha's renowned architects of the past include: John Latenser, Thomas Rogers Kimball,  George Prinz, and John and Alan McDonald.  Modern architecture in Omaha has a luminary in Donald P. Polsky (FAIA), who studied under Richard Neutra.   

Unfortunately Omaha has a terrible record when it comes to historic preservation.  The Jobber's Canyon Historic District was demolished for ConAgra campus, and one of only two Cinerama theaters left in the US, the Indian Hills, was razed for a parking lot by Methodist Hospital.
