Wilton Shopping Centre first opened in 1979 and underwent an extensive extension in 2003 which included the addition of a Tesco Superstore (owner occupied) and 11 large units. In 2007, Penneys took occupation at the northern end of the scheme.

The centre extends to approx. 11,277 sq m (121,388 sq ft) (excluding Tesco) of sales, ancillary and storage accommodation, predominantly over one trading level. The centre comprises an enclosed mall running north to south with Penneys anchoring its northern end and Tesco its southern end. The two anchor stores are linked via two malls situated at the eastern and western end of the centre. In addition to this there is a standalone external unit occupied by the Bank of Ireland, which extends to 664 sq m (7,146 sq ft).

The shopping centre has extensive surface car parking facilities, with over 1,000 car spaces, located around the centre allowing for direct customer access to each of the four entrances.
