At 11.20 am on Saturday 15 June 1996, the IRA detonated a large bomb in the city centre, the largest to be detonated on British soil. Fortunately, warnings given in the previous hour had allowed the evacuation of the immediate area, so this bomb caused over 200 injuries but no deaths. The principal damage was to the physical infrastructure of nearby buildings. Since then the city centre has undergone extensive rejuvenation alongside the more general efforts to regenerate previously run-down areas of the wider city (such as Hulme and Salford). This reconstruction spurred a massive regeneration of the city centre, with complexes such as the Printworks and the Triangle creating new city focal points for both shopping and entertainment. The following regeneration took over a decade to complete. The completion of the renovated Manchester Arndale in September 2006 allowed the centre to hold the title of the UK's largest city centre shopping mall. The bomb is commemorated by a plaque fixed to a nearby postbox which withstood the blast, which reads "This postbox remained standing almost undamaged on June 15, 1996 when this area was devastated by a bomb. The box was removed during the rebuilding of the city centre and was returned to its original site on November 22nd 1999".
