The church was established in the 6th century and was connected with the monastery at nearby Molana. The Kiely vault in Kilcockan is the longest, but by no means the oldest of the tombs or graves in this ancient place. People have been buried around this church for the best part of 1500 years. From about the year 1200, Kilcockan was served by the Augustinians, and this was to last until the 1540s when King Henry VIII dissolved the monasteries throughout Ireland. The cemetery remains in active use to the present day.
