In the lush green hills of Downpatrick in the southeast of Northern Ireland, a group of American tourists recently walked among the ancient ruins of Inch Abbey, where English monks once lived.
A couple of miles away, they offered a prayer at the grave of St. Patrick, the Apostle of Ireland, himself a Briton, while, in the capital, Belfast, they were confronted by the far more recent history of division in the period known as the Troubles, the 30-year sectarian conflict between Catholics and Protestants that cleaved society in two.
