The history of the Swiss Organ Museum is the result of a double protection of important musical and architectural heritage items of the Lake Geneva Region. A stopover barn, a historical monument dating from the 15th century, has been preserved in its state since the 18th century, its magnificent roof structure in particular. It represents the last remains of the stopover in Roche, built by Augustine canons for pilgrims on the Grand Saint-Bernard route.

A vast number of organs can be discovered in the museum, from a prototype made in 246 B.C. in Alexandria, to the great concert organ Tschanun, which was built in 1934 and contains 2,700 organ pipes, previously used by Radio Lausanne. There are several period instruments as well: a cardboard organ, a 6 metre high dresser built in 1778, Barbary organs, flute clocks, harmoniums or and an open organ.

There are various installations to let the general public make acoustic experiments.
