Overview
St Mary’s Church commands a prominent rise on Mary Street, overlooking the east bank of the River Barrow. The site stands as a National Monument, protected by the Office of Public Works, and presents a striking architectural contrast: the roofless medieval chancel and transepts, largely intact from the 13th century, sit alongside a modest 19th-century Church of Ireland nave that continues to host regular worship. This juxtaposition of ruin and active parish makes it one of New Ross’s most compelling historic sites.
History & Norman Foundations
The origins of St Mary’s stretch back to the 6th century, when Saint Abbán is believed to have established a monastery on this ground. The current stone structure, however, belongs to the Norman era. William Marshal, 1st Earl of Pembroke, and his wife Isabel de Clare commissioned the church, which was completed around 1210. At its height, it was the largest medieval parish church in Ireland.
The building weathered centuries of conflict and change. During the Irish Confederate Wars, its bells were stolen in 1654. By the early 19th century, the massive west aisle was demolished to accommodate the present nave, finished in 1813 with a spire added later in 1870. The medieval eastern portion remained untouched, preserving a remarkable collection of stonework and funerary monuments.
What to See: The Chancel & Transepts
The east-facing chancel is the architectural heart of the medieval church. Three lancet windows frame the space, which retains an aumbry, sedilia, piscina, and a richly carved tomb canopy. Among the floor slabs, visitors will find a cross bearing the Agnus Dei (Lamb of God) motif, a symbol closely linked to the Knights Templar. Given that a Templar settlement once operated nearby at Temple Town on the Hook Peninsula, and that William Marshal fought alongside Templar knights, the slab hints at the order’s historical footprint in the region.
Both the north and south transepts house a dense collection of medieval funerary monuments dating from the 13th to 17th centuries. Look closely in the north transept for faint medieval graffiti, including a tiny ship etched into the plaster. The south transept features three elegant lancet windows, a finely carved 13th-century male effigy made from Dundry stone, and a rare double marriage burial slab showing a woman laid to rest beside both of her husbands.
The Crypt & Graveyard
Beneath the south transept lies the crypt, the only roofed section of the medieval church. Two vaulted chambers still bear the curved timber imprints left by the original wicker-work centring used during construction. While early medieval markers are gone, 19th-century monuments to the Nixon, Tyndall, and Cherry families now occupy the space. Historically a burial ground for New Ross’s elite, the crypt was later repurposed as a coal bunker before its restoration.
The surrounding graveyard is equally evocative. Its oldest surviving stone dates to 1569, and early monuments feature skull-and-cross-bones memento mori carvings. Later 19th-century headstones shift toward scriptural scenes, tracing the town’s changing attitudes toward mortality.
Legends & Local Lore
The atmosphere of St Mary’s has long inspired local storytelling. One persistent tale speaks of a “Black Hole” beneath an arch where a soldier supposedly entered with his dog and never emerged. Another recounts a would-be thief who attempted to remove a cross from the chancel and suffered a fatal accident. While these stories belong to folklore, they reflect how the church’s imposing stonework and centuries of history have shaped the local imagination. Isabel de Clare, daughter of Strongbow, is also said to have her heart interred here. A cenotaph inscribed with Isabel Lagen marks the tradition, linking the site to one of medieval Ireland’s most powerful figures.

Extending Your Visit
St Mary’s sits within easy walking distance of New Ross’s town centre and the Kennedy Bridge. If you have time to explore further, consider a short drive to Ferns to see its cathedral and castle, or head south to Duncannon for coastal walks and 16th-century fortifications. The River Barrow Blueway also runs nearby, offering a paved route for walking and cycling that connects directly to the church grounds.
Bring a camera with a decent low-light setting and take time to trace the Dundry stone effigies and Templar carvings at your own pace. The €1 key system means you can step inside without waiting for staff, making it an efficient stop before lunch or a riverside walk.
