The oldest mention of an organist at the Moritzkirche in Olomouc is from 1496. In 1716 a new positive was built for the Marienkapelle.
In 1730 a large empty organ case was built. In it sat Michael Engler from Breslau a three-manual organ with 44 votes . In 1843 two registers were replaced by Christoph Erler. Otherwise the instrument remained without further major interventions.
