The instrument wa inaugurated in a special concert in Katowice, Poland, on Friday 13 January. Under construction since April 2017, and the largest instrument ever built by the Slovenian organ builders Škrabl, the new organ has cost 20.6m Polish Złoty (PLN), roughly £3.9 million. The organ is built in the French Symphonic style, and is inspired by the instruments in Rouen Cathedral and Notre-Dâme de Paris. The basic modelling follows the broad concepts set down by the pioneering 19th-century organ builder Aristide Cavaillé-Coll. To these concepts, however, it adds cutting-edge technology such as electromagnetic, electronic and fibre-optic systems. The new organ makes a grand addition to Katowice's 1,800-seat NOSPR concert hall, which opened in 2014 and serves as home to the National Radio Symphony Orchestra of Poland.
