Galway Cathedral is home to two superb organs which play different roles both in the liturgy and in concert performances.
The Gallery Organ

The organ has three manuals and pedals, and 59 speaking stops. It is located on the north wall of the Cathedral, directly above the choir gallery, with portions housed also in chambers within the Cathedral's two towers.
More information and photographs are available on the Irish Pipe Organ Website.

The Choir Organ
In 2006 the Cathedral acquired a moveable one-manual instrument with four registers. This organ resides normally in one of the side-chapels, where its primary use is in smaller-scale liturgies held in these chapels; however, it can be moved anywhere on the the floor of the Cathedral, and is capable of accompanying a good-sized congregation. It is also used in a continuo role in concerts. More information and photographs are available on the Irish Pipe Organ Website.
