Queen Elizabeth II's Historic Visit To Ireland - Day Two

DUBLIN, IRELAND - MAY 18: Irish President Mary McAleese makes a speech as she attends the State Dinner on the second day of Queen Elizabeth II's State Visit, at Dublin Castle, on May 18, 2011 in Dublin, Ireland. The Duke and Queen's visit to Ireland is the first by a British monarch since 1911. An unprecedented security operation is taking place with much of the centre of Dublin turning into a car-free zone. Republican dissident groups have made it clear they are intent on disrupting proceedings. (Photo by Arthur Edwards - Pool/Getty Images)
