A turn-of-the-century view of the mall's fully-enclosed court area. It served as a connection between the original shopping plaza and newer South Mall. When originally conceived in the early '60s, the area was known as Evergreen Square. By the time of this image, its official name had morphed to Center Square.

The PLAZA Carson's, which opened its doors -as part of the South Mall expansion- in March 1963. The 250,000 square foot store replaced a smaller specialty store location in the original shopping center.

An early 2000s view of the north shopping concourse. Office Depot assumed the old Walgreen's spot after that store closed, in 2005. Alas, Office Depot shut down in 2008. Planet Fitness moved into the space soon after.

In a circa-2008 plan, areas rebuilt since the 1960s are shown in light gray. The gigantic parking garage, once touted as one of the largest in the USA, was demolished in 2003...along with a shuttered Evergreen Theatre. By this time, THE PLAZA mall was in a downward spiral that it will never escape from.
