The history of the cathedral organ
the organ gallery in Roskilde Cathedral contains parts dating from the middle of the 15th century.
In 1555 a new organ was built here by the Dutch organ builder Hermann Raphaëlis, who perhaps had been summoned to the country for this very purpose. The façade of the Rückpositiv and the parapet of the gallery stem from this instrument.During a thorough rebuild begun by Johan Lorentz and continued by Gregor Mülisch and (probably) Peter Karstensen, the organ acquired its present main façade which bears the date 1654.
