On September 19, 1854, Ludwig Mooser came from Salzburg to Esztergom (Gran) to build a new organ there. The individual parts were transported by ship across the Danube. On August 31, 1856, it was inaugurated with the new cathedral in the presence of Emperor Franz Josef. Franz Liszt conducted the Graner Mass ( Missa Solemnis ), which he had composed especially for the occasion. The organ was the largest in Hungary with 49 stops on three manuals and 3,530 pipes . The third manual was constructed with a cone chest with the first swell mechanism in the country. The instrument soon showed some shortcomings, the mechanical action was cumbersome, and the wind supply was insufficient under heavy loads.
During the First World War, the tin pipes had to be handed in from the prospectus. In 1924 they were replaced by zinc pipes from the Angster company . The organ was damaged in World War II. In 1947 Otto Rieger built a new instrument in a side part of the case. Many original organ pipes disappeared or were improperly shut down.
From 1978 to 1979 the Hungarian organ builders Gyula Vági and János Farkas began restoring the Mooser organ. To do this, they collected the historical pipes that were left and added new ones. For this purpose, a new large organ was designed, which should have 145 registers and would be the largest in Hungary. In 2012, 89 registers were installed.
Since the death of István Baróti in the summer of 2014, Péter Kováts has been titular organist at Esztergom Cathedral.
