The queen's visit to Croke Park during the second day of her landmark visit to the Republic of Ireland will highlight the vast improvement in Anglo-Irish relations.
The visit to Croke Park is highly symbolic as it will bring the queen to a large stadium that is a revered spot for Irish nationalists.
She will also make what is expected to be her only public speech of the visit during a state dinner hosted by Irish President Mary McAleese, who invited the queen to visit Ireland.
On a lighter note, the queen plans to start her day at the Guinness Storehouse, one of the most popular tourist sites in Ireland. She and her husband Prince Philip are set to visit the Gravity Bar there -- she may well be offered a pint despite the early hour.
The British monarch also plans to meet with Irish Prime Minister Enda Kenny and to visit the Irish National War Memorial Garden at Islandbridge.
Her visit has dominated Irish newspapers and TV reports, which have offered detailed coverage of her visit since the moment she arrived. Many approved of her arrival outfit, which emphasized emerald green.
Despite the friendly welcome, the queen will still be protected by an exceptionally large security contingent including more than 8,500 police backed by troops.
Much of downtown Dublin was closed to motorists and pedestrians Wednesday morning as a large security cordon was established.
There were several scuffles and protests on Tuesday after the queen's arrival.
After Wednesday's heavy schedule, the queen plans to visit the Irish National Stud Thursday to indulge her love of horses.
She also intends to host a gala dinner for Irish dignitaries Thursday evening.
