[3] That church was part of a Dominican Abbey, whose buildings were re-used after the Reformation by the 'Gelehrtenschule des Johanneums' ('School of St John's Scholarship').
[6] Schnitger used at least ten stops from the previous organ, an instrument of an unknown builder from the late Renaissance (probably from 1567).
The pointed side towers and flats of the two cases are respectively united under a common cornice in composite style.
[7] The richly decorated cornices, stands and friezes of the facade echo the appearance of the previous instrument, or perhaps parts of the old ornamentation were re-used.
[10] The case-pipes (along with those from the organ in Oederquart) are the only ones by Schnitger's hand that have completely survived today, their metal luckily not having been requisitioned in the 20th century for military purposes.
Also unusual is the chromatic arrangement of the pipes on the free-standing pedal chest, which is explained by the slope of the western wall in St.
The organ was dismantled and stored in 1813 by Joachim Wilhelm Geycke; the Church was demolished in 1829, and later the monastery also.
Geycke and Johann Heinrich Wohlien packed the organ in wooden boxes, which were transported from Hamburg to Cuxhaven by ship.
Johann Georg Wilhelm Wilhelmy (Stade) signed a contract in which he undertook to rebuild the organ for 385 Reichstaler and set it up.
Due to the lower ceiling height compared to Hamburg, the Christ and angel figures could no longer be placed on the main case and were instead used on the pulpit and altar.
In 1928 Christhard Mahrenholz highlighted the special importance of the organ in a report and recommended a renovation and repair of those stops which were then unusable.
