The 1960s Bull Ring Centre had problems from the beginning and was very much a product of its era. At the time of its opening it was considered the height of modernity, but higher rentals within the shopping centre meant that traders turned away from it. The public were also less inclined to use the subways and escalators, which stopped working regularly. Also, it did not age well and soon became generally regarded as an unfortunate example of 1960s Brutalist architecture, with its boxy grey concrete design and its isolation within ringroads connected only by pedestrian subways. It was, by the 1980s, much disliked by the public and contributed to the popular conception that Birmingham was a concrete jungle of shopping centres and motorways.
