Kildermot Abbey was founded
Premonstratensian Canons (Norbertines), who were already established in the area at this time. It is possible the Abbey and its townland are now known as Kildermot due to patronage by the
Mac Diarmada; no connection to any St Dermot can be claimed. The Abbey was partially destroyed after the
Penal Laws of 1697. Two
holy water fonts from the Abbey were recovered from the lake by a Mr. Thomas Gallagher. One has been returned to the Abbey, while the other is in the
National Museum of Ireland. Kildermot Abbey became a
National Monument in 1939. Dawn
Mass is celebrated annually at the ruins on
Easter Sunday. ==Building==
