That deliberate concealment was not accidental. The Bridge Street Roman Catholic chapel, sitting within the parish of St. Audoen's, was the kind of place that Catholic Dublin had learned to keep quiet about, orientated east to west on its long axis and approached from a lane off Cook Street to the south or from Bridge Street to the west. The Ordnance Survey's later twenty-five-inch map still labels the site 'Chapel Yard', one of the few traces that survived long enough to be recorded before disappearing entirely.

The chapel's history was bound up with the Dominican order through most of its life. According to a 1749 account compiled by Nicholas Donnelly, writing in 1904 from earlier sources, it was assigned to the Dominican Friars by Stephen Egan, who served as prior, then provincial of the order, and eventually as Titular Bishop of Clonmacnoise and later Bishop of Meath. The building was substantially rebuilt through contributions gathered by Christopher Dillon, then prior, with additional support from a friar named Michael Shea, and further improvements followed under a succession of ex-priors: Terence Reilly, Lawrence Richardson, John Fottrell, and Dom. Shanley. By 1749 the interior was notably well furnished: a gilded and painted altar with lofty pillars, an altarpiece depicting the Crucifixion, several additional paintings including the Nativity and the Assumption, a silver lamp hanging before the altar, and a silver plate on the Tabernacle door. Lord Kingsland maintained a large pew near the pulpit, his coat of arms displayed on it, which gives a sense of how the chapel functioned as a place of worship for both the religious community and prominent Catholic laypeople at a time when public Catholic practice remained legally precarious. Cook Street in the seventeenth century had already sheltered Dominican worship, and Donnelly noted that the area had become something of a sanctuary for the persecuted. In 1764 the chapel passed from the Dominicans, who relocated to Denmark Street, to the secular clergy, serving thereafter as the parish chapel of St. Audoen's until 1846, when a new church on High Street made it redundant. The Dominicans themselves moved again in 1866, to their church on Lower Dominick Street.

Nothing of the chapel itself now survives above ground. Donnelly, writing in the early twentieth century, noted that all physical traces had disappeared only recently, though the Chapel House was still standing at that point and being used as tenements. The site lies in the area between Bridge Street and Cook Street, west of the old city core, and Rocque's 1756 map remains the clearest guide to where the building once stood. Anyone curious about the geography of Catholic Dublin in the penal era will find N.T. Burke's 1974 article 'A Hidden Church', published in Archivium Hibernicum, a useful companion to walking this part of the city.
