The Rysum organ in Rysum Church in Rysum, north Germany, is the oldest instrument of its kind in northern Europe that still largely has its original pipes. It is also one of the oldest playable church organs in the world alongside those in Sion, St. Valentin in Kiedrich, and Ostönnen. The exact date of its construction is not entirely known, but dates of 1457 and 1440 have been proposed. It was rebuilt in 1513. After undergoing several other modifications through the years it was restored to its 1513 condition by Jürgen Ahrend and Gerhard Brunzema in 1959. The organ has seven stops on one manual.
