Pipe organ in St. Peter und Paul, Baroque pipe organ in Saint Peter and Paul Church, Görlitz, Germany

The Sonnenorgel is the organ of St. Peter and Paul Church in Görlitz. Its 1703 case by Johann Conrad Buchau incorporates 17 suns made of organ pipes; twelve of them sound a twelvefold pedal mixture. The current instrument, built by Mathis Orgelbau from 1997 onward, has 96 registers on four manuals and pedal.

Eugenio Casparini and his son Adam Horatio built the organ from 1697, after a fire damaged St. Peter and Paul in 1691; it had 57 registers and was inaugurated in 1703. Schinkel and Buckow repaired it in 1827–1828, Jahn enlarged it to 64 registers in 1845–1847, and Schlag & Söhne installed a new 53-register instrument in 1894, keeping the case. Sauer built an 89-register organ in 1928, and Mathis Orgelbau, starting in 1997, created today's 96-register instrument.

The instrument is called the Sonnenorgel because of the gilded suns decorating its case. Anyone who looks up toward the gallery immediately notices these golden ornaments standing out against the wooden structure.

The organ stands on the church gallery, where you can see the full instrument from below or from nearby. Visiting during a concert or service gives you the chance to hear it played live.

The Sonnenorgel has a register called the Sonnenmixtur, made of 12 pipe ranks placed directly behind the decorative suns on the case. This register produces a bright, shimmering tone that mirrors the look of the golden ornaments.
