About 100 years ago an old disused Catholic Church overlooking Crosserlough Lake was used as a school. It was a thatched building with a roof made of black bog oak. The floor was made of clay. The children sat on round pieces of turf cut in the bog with a slane, and dried. The younger children wrote on slates with the broken stems of clay pipes and the bigger ones wrote on paper with quill pens. The teacher's salary which was a very small one was subscribed by the children every three months and the amount given by each child was about 1/-.
The foundation of this building is still to be seen in the old graveyard at Crosserlough.
A man named Patrick Campbell a native of Crosserlough is supposed to have been a poor Scholar. He used to go from place to place teaching the children of people who could afford to pay him. A son of his afterwards became a National School Teacher.
