2 metres thick, survives in the grounds of St Mary's Convent in Limerick City. It does not announce itself. Yet embedded in that wall, for anyone who takes the time to look closely, are sandstone window jambs with chamfered and rebated edges, a groove 10 metres long cut to support floor joists that no longer exist, a row of drainage chutes at height, corbels that once carried a roof, and a twin-light pointed window with a quatrefoil above it, the kind of detail that takes skill and intention to produce. Scattered in the garden nearby are dressed stones that include what appears to be part of a chimney mantle bearing the initials WMC, heraldic shields, tracery fragments, a stone lettered SFA, and one carrying a partial Latin inscription. The wall is what remains of the Dominican Priory of St Saviour, and it is considerably more layered than a single surviving wall has any right to be.

The priory was founded in 1227 by Donnchad Cairbreach O'Brien, king of Thomond, making it one of the earlier Dominican foundations in Ireland. The Dominicans, also known as the Friars Preachers, were a mendicant order who typically settled in towns rather than in remote locations, and Limerick, already a significant urban centre, suited that purpose. The buildings suffered badly in an attack on the town in 1369 and were in such poor condition by 1377 that the king made an annual grant of 40 shillings towards their repair. A map from 1590 shows what the complex still looked like at that point: a tall belfry without battlements, four ranges of buildings in reasonable repair, and the side arcades or windows of a church already ruined. Excavations in 1975, carried out by Shee-Twohig ahead of road construction, uncovered three medieval slab-built graves and evidence suggesting a transept once existed on the south side of the church, along with quantities of English and French pottery and inlaid tiles. Later excavations by Aegis Archaeology found articulated burials oriented east to west, the foundations of the church's southern wall some 8 metres from the surviving northern wall, and the lower courses of the medieval town wall.

The remains are within the grounds of St Mary's Convent, so access is not straightforward in the way a publicly maintained ruin would be. The north wall itself rewards close inspection: the cloister gable line can be traced 13 metres from the east end, and the sequence of window types along the wall, lancets, blocked doorways, a twin-light with quatrefoil, tells a story of construction and alteration across different periods. The blocked recesses and doorways, some with mixed sandstone and limestone jambs, suggest the wall was adapted rather than simply built and left. The dressed stones gathered in the garden, with their heraldic carvings and fragmentary inscriptions, are the kind of detail that tends to disappear quietly into rubble elsewhere.
