The Republic of Ireland is divided into 30 administrative regions, mostly tied to the 26 constituent counties (county Tipperary is divided in two and county Dublin in four).
The predominant religion in Ireland is Christianity, with the largest church being the Roman Catholic Church. Ireland's constitution states that the state may not endorse any particular religion and guarantees freedom of religion.
In County Dublin, part of the province of Leinster, Dublin lies nestled around the mouth of the river Liffey and Dublin Bay on Ireland's east coast.
