Due to intense opposition, Great Britain did not have a US-style, suburban shopping mall until the mid-1970s. BRENT CROSS CENTRE, the nation's first, opened its doors in March 1976.

In an early 1976 snapshot, we see a nameplate being attached to the up-and-coming John Lewis anchor store. It was to comprise 3 levels and include a balcony Wine Bar, in-store restaurant and Rooftop Garden.

On the opposite end of the dumbell plan mall stood a Fenwick ["fin-ik"] department store. Also housing 3 levels, it featured a beauty salon and Window of the World restaurant. At the time of its completion, the BRENT CROSS Fenwick was the second-largest store in the chain.
