The Queen and the Duke of Edinburgh made a historic visit to Ireland in 2011, which came 100 years after the last visit by a British monarch, when her grandfather King George V visited as part of his 1911 accession tour.
During their official trip, Her Majesty visited the National War Memorial Gardens, Croke Park stadium, the Guinness storehouse and she received widespread praise for delivering a speech on relations between Ireland and the UK, by speaking Irish.
