Westfield Stratford City is a shopping centre in Stratford, London. The centre opened on 13 September 2011. With a total retail floor area of , it is one of the largest urban shopping centres in Europe. It is the third-largest shopping centre in the United Kingdom by retail space behind the MetroCentre and the Trafford Centre. Taking the surrounding shopping area into account, it is the largest urban shopping centre in the European Union in terms of size.
Westfield Stratford City is adjacent to the London Olympic Park, East Village, Stratford Regional and Stratford International stations. The shopping centre is part of a large multi-purpose development project called Stratford City. It is promoted as contributing significantly to the local economy, with the creation of up to 10,000 permanent jobs, including 2,001 jobs going to people in the local area. However there are counter-reports of the centre having a significantly negative impact on local businesses due to the preponderance of chain stores.
In July 2012, a number of banners in Arabic welcoming shoppers for the Olympics were found to be translated incorrectly.
