Religion in the Republic of Ireland
Christianity is the largest religion in the Republic of Ireland based on baptisms. Irish Christianity is dominated by the Catholic Church, and Christianity as a whole accounts for 82.3% of the Irish population. Most churches are organized on an all-Ireland basis which includes both Northern Ireland and the Republic of Ireland.
Irish travellers have traditionally adopted a very particular attitude to the Catholic Church, with a focus on figures such as "healing priests". More generally a tradition of visions continues, often outside of Church sanction.
Culture of Ireland
Christianity in the form of both Roman Catholicism and Protestantism is the most widely practiced religion in Ireland. Christianity was brought to Ireland during or prior to the 5th century and its early history among the Irish is in particular associated with Saint Patrick, who is generally considered Ireland's patron saint. The Celtic festival of "Samhain", known as Halloween, originated in Ireland and is now celebrated all over the world.
