Organs in the Constantine Basilica

The Constantine Basilica in Trier today has two organs: a choir organ with 30 stops on two manuals and pedal, as well as a new main organ by the organ building company Eule at the back wall since 2014.
As part of the first reconstruction of the basilica, it also received an organ. This instrument was built in 1856 by the Ibach brothers from Barmen and had 40 stops, distributed over three manuals and pedal. In the two pedal towers, the pipes of the pedal register Principalbass 32′ were visibly present. The organ case was about 15 m high, 10 m wide, and 5 m deep. In 1913, the instrument was rebuilt by the organ building company Friedrich Weigle and extended to 50 stops. The actions were pneumatic. This instrument was destroyed on August 14, 1944, by a bombing raid.
