The Irish Pipe Organ Page is a website devoted to the pipe organ on the island of Ireland. It contains news, organ specifications and much more.
In 1812 an organ was purchased and a gallery erected for it at the western end of the nave.
In 1861 a new organ was procured at a cost of £300 from Telford and Telford Organs Builders of Dublin. The organ was removed in 1965 as it was in a very poor condition and the on-going costs seemed impossible at the time.
In 2007 a new organ was moved and restored by Neilands of Wexford, from the Closed Church of St. Michael-on-the-Mount-Without in the City of Bristol, England. It was installed on to the North Bay of the Crossing of the Great Nave.
This organ was built at the price of £420 by Abbott & Smith of Leeds in 1903. It replaced an earlier instrument of which little is known except that it is reputed to have been transferred to Newmarket-on-Fergus (Church of Ireland) in Co. Clare and was scrapped in recent times. The original specification of this instrument was typical of its builders work of that period, in that the specification and voicing lacked definition or brilliance.
The organ of St Agatha's Church was installed by the Dublin firm of J. & H. White, shortly after the completion of the building in 1908. It incorporated casework and pipework from an earlier instrument built by the elder John White around 1860. Originally located in a side chapel at ground level, the organ was moved to the newly constructed gallery in 1947.
