Overview
St Mary’s Church sits on a prominent rise on Mary Street, looking out over the east bank of the River Barrow. The building is a striking juxtaposition of two eras: the roofless medieval chancel and transepts, largely intact from the 13th‑century foundation, and a modest 19th‑century Church of Ireland nave that still hosts regular worship. The site is a National Monument and is protected by the Irish Office of Public Works.

History
The story of St Mary’s begins long before the stone walls we see today. In the 6th century, the saint‑named Abbán (also recorded as St Abban of Magheranoidhe) is believed to have founded a monastery on this very spot. Over six hundred years later, William Marshal, 1st Earl of Pembroke – often called the Greatest Knight – and his wife Isabel de Clare commissioned the grand parish church that would become the largest medieval parish church in Ireland. Construction was completed in 1210.
The church survived the tumult of the Irish Confederate Wars; its bells were stolen in 1654 by a Lieutenant‑Colonel Beale. Divine services continued until the early 19th century, when the massive west aisle was demolished to make way for the present nave (finished in 1813, with its spire added in 1870). The medieval portion – the chancel, north and south transepts – remained untouched, preserving a treasure‑trove of funerary art.
Local folklore adds a darker hue: stories of a “Black Hole” under an arch where a soldier entered with his dog and never returned, and a grisly tale of a man whose brain was smashed when he tried to steal a cross from the old chancel. These legends, together with the church’s genuine medieval features, give the ruin an atmospheric allure.
Templar Connections
One of the most striking carved slabs in the chancel bears the Agnus Dei (Lamb of God), a motif strongly associated with the Knights Templar. Historical research notes that a Templar settlement existed nearby on the Hook Peninsula at Temple Town, home to the famous Temple Church. William Marshal fought alongside Templar knights during the Crusades, and it is plausible that some of the order were buried here. The presence of the Templar‑linked cross slab, together with the church’s Norman patronage, makes St Mary’s a point of interest for anyone tracing the medieval military orders in Ireland.
What to See & Do
The Chancel
The east‑facing chancel houses an aumbry, sedilia, piscina and a richly carved tomb canopy. Three lancet windows illuminate the space, showcasing early Gothic stonework. Among the stone slabs is a cross bearing the Agnus Dei, and a second slab, known locally as the Bambino Stone, depicts a swaddled child.
North & South Transepts
Both transepts retain a remarkable collection of medieval funerary monuments, ranging from the 13th to the 17th centuries. The north transept features faint medieval graffiti – a tiny ship etched into plaster, perhaps left by a travelling pilgrim. The south transept contains three elegant lancet windows and a fine 13th‑century male effigy carved from Dundry stone. A rare burial of a woman beside both of her husbands can also be seen here, an unusual arrangement for the period.
The Crypt
Beneath the south transept lies the only surviving roofed part of the medieval church: the crypt. Two vaulted chambers, once supported by wicker‑work centring, still display the curved timber imprint on the ceiling. While the original medieval burial markers have vanished, 19th‑century monuments to the Nixon, Tyndall and Cherry families now stand within. The crypt once served as a burial place for the town’s elite and, in the 20th century, was repurposed as a coal bunker.
Legends of Isabel de Clare
Isabel, daughter of Strongbow and granddaughter of the Gaelic King Diarmait Mac Murrough, is said to have her heart interred in St Mary’s. Though her body rests in Wales, a cenotaph bearing the inscription Isabel Lagen marks the spot, adding a romantic layer to the visit.
The Graveyard
Encircling the church is a historic graveyard whose oldest surviving stone dates to 1569. Early monuments display skull‑and‑cross‑bones memento mori, while later 19th‑century stones feature scriptural scenes, reflecting the evolving attitudes toward death.
The Norman Way & Guided Tours
St Mary’s Church is a key stop on The Norman Way, a self‑guided walking trail that links New Ross’s most important Norman‑era sites, including St Stoke’s Castle and the historic town walls. Visitors can download the free map from the Visit New Ross website or pick up a printed version at the Tourist Information Office.
Local history groups also run the William Marshal Route, a themed guided walk that delves deeper into the life of the church’s founder and the town’s medieval development. These tours usually run on weekends from April to October and can be booked through the New Ross Heritage Centre.
Events and Community Use
St Mary’s continues to serve the community as a venue for music and charitable events. Each December the church hosts a Christmas sing‑along charity concert in aid of the New Ross Special Olympics, featuring local trad musicians and the New Ross & District Pipe Band (see the Irish Independent report, 17 Dec 2023). The venue is also listed on the Journal of Music in Ireland’s calendar for occasional classical and choral performances.
These events are free to attend but may require advance booking, especially during the festive season.
