A vintage view of Centre Court at BULL RING CENTRE. The mall's interior had no natural lighting and not a lot of the artificial variety. The prevailing theory was that brightly-lit stores would draw customers inside. One might notice how the escalators bypass the Car Park Entry Level, in the middle, and connect the Centre Court Level directly with the Grand Parade Level.

The facade of the original BULL RING CENTRE, which incorporated Brutalist design principles. The structure took on the appearance of a fortress-like, concrete hulk.
