The organ was built by Compton in 1948 where it replaced a previous instrument. It is the Compton "Miniatura III" model and is built upon the extension principal consisting of 3 ranks of pipes: Diapason, Gemshorn and Flute. In 1985, the organ was moved to it's present location on the rear gallery but otherwise remains in original condition.
