The organ in the Jerusalem Synagogue, built in 1906 by the renowned Prague organ builder Emanuel Štěpán Petr, is one of the most valuable Romantic-era instruments in the country. It has 24 stops, two manuals, and a pedal, but its true value lies elsewhere—after more than a century, it has been preserved in nearly its original condition. To this day, it retains its original sound, intonation, and unique character, allowing listeners to hear the organ almost exactly as it sounded when it was first built. In order for this rare instrument to continue accompanying church services and concerts, it requires regular maintenance and repairs. Help us preserve its unique voice for future generations.
