The Church of the Holy Cross – existing in its current architectural form since the first half of the 16th century – was equipped with an organ at the turn of the 17th and 18th centuries (builder unknown). The precise date is difficult to establish; written sources confirm the renovation of the choir loft in 1683–1684 as well as the presence of the instrument in 1704.
The organ underwent multiple restorations and, at the same time, reconstructions: in 1897, 1912, and subsequently in 1927. During the latter intervention, most of the original Baroque sound-producing components were removed, including the slider windchests with pallet action together with the majority of the old pipework, the bellows, and the mechanical stop action along with the keyboards. A new instrument was then built – placed inside the historic façade case, yet equipped with technical solutions regarded at that time as modern. Consequently, the newly built instrument featured pneumatic windchests, key and stop action, and a freestanding two-manual console with pedal. The historic front pipes and two ranks – Flet Major 8′ and Cymbał – were preserved, although their names were altered to Gedekt 8′ and Cymbel. The instrument assembled in 1927 comprised 15 stops: Manual I – 7 stops, Manual II (Positiv) – 5 stops, Pedal – 3 stops.
Further work in the post-war spirit was carried out in the 1950s and 1960s. The last inspection and repair (prior to the 2003 reconstruction) took place in 1989, during which several stops were replaced – among them the historic Cymbał, substituted with a Quinta 1 1/3′. The Cymbał pipes were deposited for storage within the parish.
The present organ is as faithful a reconstruction as possible of the original layout, which comprised two manuals with a suspended pedal. The instrument was, however, expanded by adding a new, independent five-stops pedal division. The organ also received two new wedge bellows, operable either by a calcant or an electric blower, new slider windchests and a mechanical suspended key and stop action. A built-in two-manual console was installed within the case (diatonic keys covered with ebony and furnished with decorative front panels; chromatic keys made of white beechwood, topped with bone) together with an oak pedalboard.
