This was the original parish church of Ballylongford. The present structure dates from the 15th century, and it replaced an earlier one from the 6th century.  After the Cromwellian conquest was completed in 1653, the church was taken over by the newly arrived Protestant Community.  It was in this church that Herbert Horatio Lord Kitchener of Khartoum, Britain’s leading military strategist during World War I, was baptized in 1851.
