Where's the largest pipe organ in the world?

Built between 1929 and 1932, the largest pipe organ in the world is the Atlantic City Convention Hall Organ, in Atlantic City, New Jersey, USA. According to the Guinness Book of World Records, it is also the largest and loudest musical instrument ever constructed.

The monster music maker has 336 stops (tuned sets of pipes that form musical voice settings), and is powered by blowers totaling more than 600 horsepower. The exact number of pipes is not known; the quoted figure is 33,112 but some experts estimate the number at more than 32,000.

The main playing console, which is surrounded by art-deco columns with stylized flames on top, boasts seven keyboards and rank upon rank of stop controls. There are six large foot pedals and dozens of small ones. The pipes are located in chambers that fully surround the auditorium, so the audience is completely immersed in the musical experience.
