It was a royal occasion with Princess Anne there to perform the opening duties.
Since then, we have seen shops of all varieties come and go.
But let’s go back to the very early days for a look at the shops we first knew and loved – as well as a reminder of that opening day.

6. A cuppa and a browse at Binns
Binns store was a favourite with shoppers with its popular cafe and huge range of departments. Did you like to pay a visit? | JPIMedia Resell Photo: HM
7. Pop in for a pint
A favourite pub for many - and right on the edge of Middleton Grange - was the Clansman which first opened in 1972. What are your earliest memories of it? | JPIMedia Resell Photo: HM
8. Such a big crowd
The opening of the shopping centre wasn't the only duty for the princess. She also officially opened Hartlepool College of Art. | JPIMedia Resell Photo: Hartlepool Mail
