Errew Abbey, Errew, Co. Mayo

Yet at the furthest reach of a peninsula that pushes out from the western shore of the Connacht lake, a small Augustinian community once maintained a church, a cloister, and a dormitory, the whole ensemble occupying ground that feels less like a chosen site than an island that simply forgot to fully detach itself from the mainland.

The abbey's origins are genuinely murky. Tradition attributes the founding of a church here to St Tigernan in the 6th century, and the locality preserved a relic associated with him, known as Mias Tighernain or St Tigernan's Paten, until at least the early 20th century. A holy well nearby was also connected to the saint. The earliest documentary mention, in the Annals of the Four Masters, describes a Bishop of Cork who died in 1172 as being 'of the family of Errew Lough Conn', which suggests the place had some standing by then, though it tells us little else. The Barrett family became closely bound up with the abbey; Thomas Barrett, Bishop of Elphin, was buried here in 1404. Nine years later, a man named Robert MacWattin forcibly dragged Henry Barrett from the abbey's sanctuary, and was subsequently so tormented by visions of St Tigernan that he returned his prisoner and donated a quarter of land to the community in penance. It is believed the Barretts established the Augustinian Canons here in 1413, probably as a cell of the Augustinian abbey at Crossmolina. By 1463 the community was receiving an annual grant of five shillings from the lands of Ballymoy, and when the monasteries were dissolved and an inquisition carried out in 1584, the total annual value of the abbey's possessions was assessed at thirteen shillings and four pence, a figure that speaks to how modest the house had always been.

The standing remains reward close attention. The church, roughly 25 metres long and built in coursed limestone, was refurbished in the 15th century, and the trefoil-headed windows and the elegant piscina recess, a shallow wall niche that once held a basin for rinsing sacred vessels, belong to that phase. A small round-headed window in the north wall of the chancel looks earlier, and may be Romanesque in origin. During repair works in the 1930s, a fragment of a 12th-century carved capital was found built into a 15th-century window frame, quietly recycled and invisible to anyone looking at the building today. The east ambulatory of the cloister survives intact, its arcade still carrying the upper floor of the east range above it, and a trefoil-headed window in the shared wall between the dormitory and the church was positioned so that sick or elderly monks could see into the chancel from their beds.
