Here we take a look back at times gone by at the city centre shopping complex and some of the shops that are no longer with us.
This retro photo gallery includes queues outside Virgin Megastore to see Def Leppard, customers at the Double Dutch pancake bar and crowds at Waterstones waiting to get their hands on the latest Harry Potter book in 2007.
Can you remember Elsie the buffer girl and Fred the grinder, who are also pictured?
