Queen Elizabeth II landed in Dublin today at the start of a landmark state visit to Ireland.
She began her trip by paying a visit to Aras an Uachtarain, the official resident of Irish President Mary McAleese, who greeted the Queen upon her arrival.
The Queen's visit is the first by a British monarch since Ireland won independence from London in 1921.
Security will be tight for the Queen's four-day visit, with more than 8,500 Irish police assigned to protect her and her husband, Prince Philip.
Dissident nationalists have said the queen is not welcome on Irish soil and a coded bombing warning on May 16 triggered a security alert in London.
Irish police today said soldiers defused a homemade bomb near Dublin overnight after police had been tipped off by an anonymous caller.
