The Queen has spent the day in the Republic of Ireland, during the first visit by a British monarch. After flying into Baldonnel military air base, outside Dublin, for the four-day trip, the Queen emerged wearing the symbolic colour green.
One of the Republic of Ireland's biggest security operations is in place, amid a rise in dissident republican violence. A bomb discovered on a bus outside the Glen Royal Hotel in Maynooth, County Kildare, was made safe just hours before the Queen's visit. Two other suspect packages, one near the Luas tram line at Inchicore and one in Fairview Park, turned out to be hoaxes.
The Queen was then escorted to Aras an Uachtarain, the official residence of the Irish president, in Dublin's Phoenix Park. The visit is taking place following President Mary McAleese's invitation. The Queen shook hands with Mrs McAleese at the front of the residence before moving inside to meet the Taoiseach (Prime Minister), Enda Kenny.
An Irish army band played God Save the Queen followed by the Soldiers' Song, amid a 21-gun salute. The Queen then inspected the guard of honour before lunch with guests including John Hume and Lord Trimble - two politicians who have been vital to the peace process in Northern Ireland.
As the Queen arrived at the Garden of Remembrance protesters faced police officers in riot gear who tried to push away the crowd.
During one demonstration in north Dublin, protesters pushed a burning rubbish bin towards riot police.
Much of the centre of Dublin was cordoned off, leaving many streets empty, as part of the strict security clampdown put in place for the visit.
The Queen laid a wreath completing one of the most controversial elements of the trip. The act is significant as the garden is dedicated to people who fought for Irish independence.
As part of the visit, the Queen also went to Trinity College to be shown the Book of Kells, a 1,200-year-old illuminated manuscript in Latin, containing the four gospels of the New Testament.
