Music has always been an important feature in churches. The surviving abbey documents mention that Abbot Lytlington (d.1427) had a large organ built over the main door of the abbey church with a smaller portable one for use elsewhere. The use of church organs declined after the reformation in the 16th century and it was not until the 17th century that they started to appear again in parish churches. Very few organs have survived from the medieval period and the organ at Crowland is no exception. This one on the north side of the nave dates to 1900 and it replaced an earlier one dating to the 1820s.
