The monastic stalls discussed in this article are part of the original Baroque furnishings of the post-Cistercian church at Koronowo. Their dating was verified recently by the discovery of a 1796 signature of Grzegorz Baranowski on the picture of St Benedict. The stalls are covered with heavy overlays executed in the 18th century. The aim of that alteration was, probably, to adjust the stalls to the overall aesthetic formula of the newly reconstructed church interior. The arrangement of monastic choir of which the stalls are a part was radically altered soon after the Second World War. Our investigations show that the two sections of two-tier fifteen seat stalls now in the presbytery used to occupy the first and second bay of the nave (next to the transept). At the far (western) end the stalls abutted on pillars edged with wood-carvings representing St Benedict and St Bernard. The arrangement at the other (altar) end has not changed. The twin-seat (prioral and abbatial) stalls branched sideways in the transept. The original layout of the Koronowo choir reconstructed in the article evinces numerous analogies with corresponding constructions in Cistercian abbeys in Silesia such as Lubiąż and Henrykowo. The stalls of the Koronowo church owe their originality not only to the elaborate woodwork decorations but also to the way in which the seats of two-tier stalls were mounted on a sturdy wooden framework. Moreover, the construction of the high backs enabled the 18th century renovators to adapt them for a typically Baroque chiaroscuro.
