The Irish National Heritage Park - Christian Age by Nobbe
Christianity probably arrived in Ireland by the 4th century. Early in the 5th century it was given an added impetus by the arrival of missionaries sent by the Pope in Rome. The most famous of these was St. Patrick, who arrived in 432 AD, and preached mainly in the North of Ireland. Although Christianity triumphed all over the country, traces of Paganism remained for centuries.
