I visited this church during my independent tour of Dublin and I sincerely think that's worth a visit. It's majestic and impressively tall, with a neoclassical-ish style that I personally love. It's free and you can visit it even just as a tourist.

Freestanding stone-built Greek Revival Catholic cathedral, built 1814-25, on cruciform plan with pedimented portico. Possibly designed by John Sweetman, with involvement of John Taylor and George Papworth. Altered and extended c.1835, c.1840, c.1857 and c.1928. Roof concealed by coursed granite ashlar parapet walls with replacement metal rainwater goods breaking through to re-entrant angles. Single-span pitched slate roof with ridge running east to west, interrupted in centre by large copper clad dome on octagonal base. Roof bowed to west apse with hipped slate roofs to four corner pavilions and later accretions. Deep moulded Portland stone cornice to base of parapet spanning front and side elevations with mutules and guttae having frieze below enriched with triglyphs and metopes, plain to pavilions. Coursed squared granite ashlar walls with platband at sill level, squared coursed calp limestone to rear elevation only. Prostyle hexastyle Greek Doric portico executed in Portland stone with fluted columns on raised granite plinths and full-span pediment surmounted by three statues by Thomas Kirk, added c.1845. Central double-height square-headed door opening with moulded granite architrave surround, double-leaf flat-panelled wood-grained timber doors and overpanel. Door opening flanked by marble water fonts set into walls with further square-headed door opening to either side with moulded architrave surrounds and double-leaf flat-panelled wood-grained timber doors with incorporated lights. Doors opens onto granite-paved stylobate with seven granite steps with entire east and south railed areas paved to height of raised plinth wall. Square-headed blind window to both cheeks of portico with architrave surrounds and entablature. All four projections have pedimented tripartite window opening executed in Portland stone with Doric columns fronting stone mullions, twelve-over twelve-pane timber sliding sash windows to southeast and northwest projections and fish-scale leaded stained glazing to southwest projection. Colonnaded central wing to east elevation has granite ashlar walls and five square-headed window openings with fish-scale leaded stained glass flanked by engaged fluted Portland stone Doric columns supporting Portland stone Doric entablature and parapet wall with corresponding squat piers. To central bay of colonnade is advanced granite doorcase with architrave surround, decorative frieze and cornice and double-leaf timber panelled doors. Informal rear elevation has voussoired segmental-headed recess containing tripartite window opening with granite mullions surmounted by console brackets supporting lintel cornice and having leaded stained glazing. Recessed door opening with granite surround and flight of granite steps with double-leaf timber panelled doors and wrought-iron gate. Rear elevation extends to north as single-storey granite accretion with further two-storey block having Diocletian window openings. Front and south side elevations are enclosed to street by decorative wrought and cast-iron railings and set on raised granite plinth with scrolled iron panels surmounted by crucifixes and matching iron gates. Apsidal-ended colonnaded basilica-plan interior with central raised altar below dome, side aisles and ambulatory. Principal entrance porch to east with organ gallery above (1893, dedicated to James Joseph Cunningham) supported by two slender Corinthian columns and with ornate floral balustrade and brass handrail. Decorative mosaic tiled flooring to nave and side aisles and marble flooring to altar. To southwest is parish office, with sacristy to northwest. Front of altar table carved by Peter Turnerelli in 1825 depicting pair of kneeling angels. Ambulatory contains two altars: Sacred Heart (on north side) and Blessed Virgin (on south side), dating from eighteenth century from former church on Liffey Street. Side altars to aisles dedicated to Saint Joseph (north aisle) and Saint Laurence O'Toole (south aisle) are restrained Corinthian marble aedicules of 1861 by J. Lyons.

I adore the marble status in St Mary's Pro-Catherdral, which depict the various aspects of the life of Cardinal Paul Cullen, the first Irishman to be made cardinal (by Thomas Farrell in 1881): tending the ills, weak and poor, educating and training priests etc. The texture of marble allows us to clearly vision how people were like in 150 years ago: their facial expressions, guestures, hairstyles, the folds and flows of their clothes, the proportion of their physique... the gentle glow of light through reflects on the statues, as if you can feel the warmth eminating from their bodies. When you gaze at them long enough, you might mistaken them breathing in the slow changing of daylight. If you would like a moment of quietness just 5 mins away from the noises of the O'Connell Street, this is a great place to enjoy a moment of peace.

Beautiful church inside, lovely statue's, old style candle holders. When the sunshine in morning, it lights up the alter. Well worth a visit for some private prayer and thought prayer 🤲 🙏

The building is beautiful. There are so many wonderful statues and paintings. The Mass was very nice. I couldn't believe the number of things to look at. It was like an artuseum of Iriish Catholic icons.

I love this church and the hustle and bustle on what's going on outside and go in there to play and reflect. The mass services is daily at 10.30 am and 12.45 am and always confession after the 10.30 mass on weekdays

Went here to see a Eurovision concert with 7 past winners. And, wasn't it the BEST night ever!! We saw Dana, Johnny Logan, Linda Martin, Niamh Kavanagh, Paul Harrington, Charlie McGettigan, Anna Kearney and Secret Garden perform, in which we met Niamh Kavanagh, Dana, Linda Martin and Johnny Logan after the show!! Thank you so much for an amazing Eurovision concert, and we will certainly be back for another concert!!

A beautiful Catholic Cathedral built for the faithful of Dublin as a replacement for St. Patrick's Cathedral which was once the Catholic Cathedral of Dublin. This old Lady has seen alot of history over the years and certainly is beautiful, if not a little bit tired and in need of some love. Well worth a visit to see its classical styled beauty and spend a little time in quiet reflection.

Oddly enough Dublin does not have a Catholic Cathedral. The Pro Cathedral is the Bishop of Dublins see. Situated in the city centre just off O'Connell Street it is easy to get to.

A beautiful cathedral located on Marlborough Street in the city centre. Check for opening times And suitable for all.

Just off I Connell Street, this is a wonderful, quiet oasis in the contre of Dublin. Soak up the visual feast of the imagery, surrounded by intricate painting of golden stars, glittering mosaics and the hypnotic light of the burning candles behind the main altar. It's a surprising find and you can sit and just be. The photos attached were taken there.

A special service (blessing of the chrism). Very beautiful. Palestrina Choir fantastic. More priests than I have ever seen in one place for the renewal of their vows.

Lovely and worth a visit if nearby and free for a half hour. #StMarys #Church #Dublin #Ireland #StainedGlass #Ornate #StainedGlassWindow #Organ #Marble #Pews #Cathedral #Candles #18Dec2022

Went there to see where Mt 3rd great grandfather passed away. Spiritually moving.

My first confession in Ireland was happened on October 15th 2022 @ Pro cathedral church Dublin.Week days after morning holy mass sacrament of reconciliation is possible here.Today priest told me my confession is sincere :) every confession is a great blessing moment. Enjoy the grace of God! #MinSinAtCathedral #MyWifeClicked #PicIshere.

A beautiful Cathedral, Mass times are 9:30, 11:00, and 6:30 p.m. on Sundays Some of the prayers were in Latin, some that I had never experienced in Latin before which was awesome!

I remember a couple years ago I was at mass for the vigil.some one came along and used their video camera 📹 I did n t like it .Luckly some one game along to a to tell that person to put it away .I think it is a good idea it shouldn’t be aloud .It is only right

For the first time there I founded a group from Shalom Community. Beautiful church.
