Which retailer opened the first modern shopping mall, Southdale Center, in Minnesota in 1956?

The Dayton Company opened Southdale Center in Edina, Minnesota, in 1956.

Southdale Center is widely regarded as the first fully enclosed, climate-controlled shopping mall. The Dayton Company developed the project to create an indoor retail environment that could operate comfortably through Minnesota’s extreme seasonal weather.

Architect Victor Gruen designed the center, which combined department stores, smaller shops and shared indoor public space. Its design became an influential model for suburban shopping centers built across North America in the following decades.

The Dayton Company is sometimes confused with Dayton’s department store itself, which was the project’s anchor retailer and corporate predecessor. Southdale was not the first shopping center of any kind; its importance lies in its enclosed, climate-controlled design and integrated tenant layout.
