Daniel Kern of Strasbourg, Alsace, completed a 4,873 pipe organ for the structure in April 2005 and it was inaugurated in October of that year.
The Kern organ contains all the stops which were in the original Silbermann organ and attempts to recreate their sounds.
The Kern work contains 68 stops and a fourth swell manual in the symphonic 19th century style which is apt for the organ literature composed after the baroque period. (Wikipedia)
