Organ concerts in St.James Basilica in Prague are very famous for their long tradition and absolutely unique sound of the organ instrument. The St. James´s organ is the largest organ in Prague and second largest in the Czech Republic. The organ´s case, which is still admired today, was quite unique in its time. So far the latest major reconstruction was carried out between 1981 and 1982 by "Varhany Krnov" (Rieger-Kloss). At present the organ has four manuals, 91 speaking stops and 8,277 pipes.
