3 manuals and pedal, built by Klais in 1965

This organ, built in 1965 by the Klais company in Bonn, enjoys a reputation as one of the most beautiful-sounding organs in the Braunschweig area. With its well thought-out specification, its richness of sound and its exceptional quality, it is an outstanding example of the high quality of Klais organs. The impressive acoustics of the Aegidienkirche with up to 10 seconds of reverberation also contribute significantly to the sound experience.

The organ has sounded completely unchanged since it was installed in 1965, with the exception of the addition of a registration sequencer. The organ has a mechanical action with electrically operated slider chests for the stops.
