The Altars are all of simple white marble slabs on central marble supports relieved only by bronze motifs - those of the High Altar depicting the Sacrifice of Calvary and that of the Blessed Sacrament Altar depicting the miracle of the loaves and fishes. The Tabernacle on the Blessed Sacrament Altar is of satinised bronze with burnished bronze doors designed by the architect in conjunction with R. Enda King. The Sanctuary area is completed with white and green marble altar rails, black and satinised bronze candlesticks and fittings, all over-shadowed by a blue and white relief of the Archangel Gabriel on the main back wall.

The stained glass leaded windows and Stations of the Cross were executed by the Abbey Stained Glass Studios incorporated in the Dublin Glass and Paint Co. The beaten bronze doors of the Tabernacle on the Blessed Sacrament Altar are by R. Enda King of Gill and Sons Ltd. The theme of the main front entrance stained glass window is of the Guardian Angel in the traditional role of custodian of a boy and girl. Note the outstretched arms of the Guardian Angel encompassing the world with protective care. The head-dress was, in fact, copied from that worn by Cleopatra in the block-buster film of that time! In the front entrance porch are two etched glass panels depicting the Annunciation and the Nativity.
