By the late 1970s, Dayton's ARCADE was run-down and deteriorating. The facility was given a 14 million dollar rehab. It re-emerged, as ARCADE SQUARE, in October 1980. Comedienne Phyllis Diller (1917-2012) officiated at the dedication.

A photo that I actually took! A circa-1983 view of the great Rotunda at ARCADE SQUARE shows its 3 levels and glass-enclosed elevator.
