OPEN-AIR MALL- A non-enclosed, non-climate-controlled, shopping
mall, usually with awnings on the front of stores and along its roofless
corridors. In the early days of shopping malls in America, open-air
centers were the standard. This began to change in late 1956, following
the opening of Minnesota's SOUTHDALE CENTER, which was the
nation's first fully enclosed, regional-class mall.
