The Cistercian abbey, 1217
Clarus Fons
Monks from Morimond — a daughter house of Cîteaux in Champagne — colonised Macosquin in 1217, dedicating their new house to Our Lady of the Clear Spring. The site is the rise above the village. By 1539 the place had fallen into disrepair. At Plantation the lands were granted to the London Guild of Merchant Taylors and the parish church was built into the abbey shell in 1616. The 13th-century lancet window in the north wall of St Mary's is the surviving piece of stone. Everything else is foundations under the grass.
An older monastery on the river
Camus-juxta-Bann
Two miles east of the village, at Castleroe on a bend of the Bann, lies Camus — Camas-Comgaill in older spellings. A monastery attributed to St Comgall of Bangor in the sixth century. The site overlooks what was a known ford on the river. The parish name 'Camus-juxta-Bann' — Camus next to the Bann — kept the link alive in the church records for centuries. What's left is the graveyard and the broken sandstone high cross.
Used as a gatepost
The high cross stock
The Camus high cross stood in the graveyard until the mid-1700s, when it was broken — accident, lightning or vandalism, no one's sure. The remaining stub was reused as a gatepost into the churchyard for a stretch before anyone realised what they'd done. It's sandstone, carved with the Ark, the murder of Abel, and the baptism of Christ. It's still there. Park at the gate on Curragh Road and walk in.
How the village got its grid
The Merchant Taylors' Plantation
The Plantation of Ulster carved Derry up among the London livery companies. Macosquin and its lands fell to the Worshipful Company of Merchant Taylors. The grid you walk today — the church on the rise, the main street running off it, the lanes laid out at right angles — is theirs. The abbey was already a ruin by 1609 when James I handed it across. The Merchant Taylors took the stone, kept the church, and built a village around what was left.
