Iskaheen has links to the earliest Christian tradition in Ireland.
In the year 443, Patrick converted the people to Christianity and baptised Eoghan.
Eoghan was the son of Niall of the Nine Hostages . He was buried at Iskaheen in the year 465.
St. Patrick’s in Iskaheen (1782) is one of the oldest churches in the Derry diocese still in use.
Before St. Patrick’s opened, penal laws were in force from the Battle of the Boyne (1690) to the end of the Jacobite era of 1745, in which Catholics held no land, public office, no access to education, and no freedom to practice their religion.
During the penal laws, it was not safe for a Bishop to be consecrated or live in Derry city itself. A Dr McColgan was elevated to the See of Derry around 1760. In 1765 he was driven to live in a limekiln at Muff, which was then in Co. Derry and was only able to visit Derry under the cover of night to avoid arrest and exile.
With the relaxation of penal laws, Dr. McColgan became the first Bishop of Derry to live in the city for 190 years.
