Kilmasantan (Ceall Easpaig Shantáin/Kilmasanctan/Kill Sanctan) Church ruins (DU025-033001-) annotated St Ann's (Sanct-Anna) Chapel on historic OSi maps, stands on an early Christian monastery founded by St Santán, whose feastday falls on the 9th of May and 10th of June (Ó Riain 2011, 546-7; O'Hanlon 1875-1903, Vol. VI, 614). St Santán also known as Bishop Sanctan, probably founded the monastery here in the 6th-century. Santán, was son Samuel Ceanníseal, 'head-bent' (Sawyl Benisel in Welsh genealogies), brother of the pilgrim Madóg (from Welsh Madawg) and his mother was Deichtir daughter of Muireadhach Muindearg, king of Ulster (Ó Riain 2011, 546; Baring-Gould & Fisher 1913, 171). In the Isle of Man, a parish was named Kirk Santan after the saint who, as in Ireland, was later confused with St Ann (ibid.). In the year 962 AD, The Annals of the Four Masters recorded the death of 'Caenchomraic, abbot of Cill Easpuig Sanctan'. Situated in the upland river valley of Glenasmole, in the Dublin Mountains, on the W facing slope of rising ground overlooking the E bank of the River Dodder. Inside the gate of the graveyard (DU025-033002-) immediately to the N there is a medieval font (DU025-033003-). Adjoining the NW side of the graveyard are the remains of a circular-shaped area enclosed by an earthen bank which may represent the remains of an ecclesiastical enclosure (diam. c. 65m) associated with the early Christian monastery of Kilmasantan. The curving field bank on the N side forms the townland boundary with Glassamucky to the N and Ballymorefinn to the W. St Ann's Well (DU025-018----) originally St Santan's Well lies 175m to the NE.
