Errigal Old Church
It is believed that a small church was built at Errigal around 560 A.D. It was originally a Columbian foundation that prospered until the 9th Century when it was sacked by Danish invaders. The Church was attacked and rebuilt many times until it was completely destroyed after the 1641 rebellion and a new Church was then built in the village of Garvagh in 1670.
In the early days the Church was called "Errigal- Adamnan" (Adamnan's Church) after St. Adamnan, its patron. Another feature bearing the patron's name is Onan's Rock. (Onan means Adamnan) found near the old Church and unusual because of the footprints (said to be Adamnan's) impressed on the rock.
