Above the west door is the organ gallery. The organ has recently been rebuilt by the internationally acclaimed Kenneth Jones of Bray. The original casing has been retained and extended and the pipes have been elaborately stencilled and gilded. The organ is a four manual instrument that can be played from the gallery or at the consul at the front of the santuary. Above the organ gallery is the west window which has a central panel showing Christ conferring the keys to St Peter. On either side there are depictions of St Patrick and St Malachy, the National and Diocesan Patrons. Other panels show the Holy spirit and the heraldic arms of the Diocese and also of Pope Benedict XV. The side panels depict emblems of the Passion and a Monstrance with the Blessed Sacrament, appropriate for a Cathedral with perpetual adoration.
