St David's (previously known as St David's Shopping Centre.) or more formally St David's Dewi Sant, is one of the principal shopping centres in the city centre of Cardiff, Wales. It is in The Hayes area of the southern city centre. Owing to the extension of St David's 2 in 2009, St David's is now the ninth largest shopping centre in the United Kingdom. The construction of the extension cost a total of £675m and brought Cardiff within the top five shopping destinations in the United Kingdom.
