Queen to visit Cashel, Cork to end Irish trip.

Queen Elizabeth II is visiting the medieval Rock of Cashel, an old English Market in Cork and a high-tech research facility Friday before returning to England at the conclusion of her four-day tour.The ambitious trip has been hailed by many as consolidating a new era of cooperation between England and Ireland, two neighbors that have often been adversaries. The queen, who wore bright green as she touched down at the Rock of Cashel on Friday, has been praised in Irish newspapers and television commentary for her sensitive approach to the difficult history between the two neighbors.

She and her husband, the Duke of Edinburgh, were twice applauded by onlookers as they made their way across the medieval site, which sits on a limestone outcropping in southwest Ireland.

She was driven to St. Patrick's Cathedral, an ancient, ruined church in a green Bentley, and was shown around while children from the Cashel Community School choir sang the Gaelic blessing, "May The Road Rise To Meet You."

Cashel Community school music teacher John Murray said "everybody in Cashel and the school are honored to have the queen here."

Still, the queen's trip has been marred by a massive security presence to protect her from dissident attacks and by the discovery Tuesday of a bomb hidden on a bus. It was found and neutralized before it exploded.

In Cork the queen was due to visit the English Market, which has had stalls selling meat, seafood, local cheese and other goods since the late 18th Century.

From there she plans to visit the Tyndall National Institute, a high-tech institution created in 2004. It is a research hub where the queen and Philip will be briefed on current projects.

They will also meet with local representatives, including the Benhaffaf twins, who were conjoined at birth and were separated by an Irish surgeon, Dr. Edward Kiely, at London's Great Ormond Street Hospital.

The queen plans to spend the weekend in England before receive President Barack Obama and his wife Michelle at Buckingham Palace next week.
