Mather Tower

Mather Tower is a skyscraper in Chicago that combines a rectangular base with an octagonal tower rising approximately 159 meters across 42 floors. The distinctive shape and proportion make it recognizable among the city's tall buildings.

This building was completed in 1928 when it became the city's tallest structure during a period of economic growth. Later recognition came in 2001 when it received designation as a Chicago Historic Landmark.

The tower received recognition as a Chicago Historic Landmark in 2001 and garnered the National Preservation Honor Award in 2006 for architectural excellence.

The lower levels house a hotel with guest accommodations, while the upper floors contain office and residential spaces. Visitors should note that this is an actively used building and access to some areas may be restricted.

The building sits on an unusually narrow base of just 30 by 20 meters, making it the slimmest high-rise in Chicago. This extreme thinness was an experimental design that pushed the boundaries of what architects thought possible at the time.
