Turlough is one of the ancient places associated with St. Patrick, where in 441 he established the church, St. Patrick’s Church, over which the Archbishop of Armagh had jurisdiction and revenue up to the 16th century.
The church was destroyed by the Cromwellian soldiers in 1654.
It was a remarkable building with solid walls and roof. Some beautiful stone works can be seen in wall, arch and window.
The western wall boasts a stone slab with the representation of the crucifixion dating around 1025.
