The condition of paintings and sculptures decorating the ceilings and covings of the garden galleries has been significantly improved. At King Jan III’s request, they were modelled on similar solutions in Italian architecture. After the removal of secondary layers of engobes and faulty restorations, the sculptural decorations gained expressiveness and refinement. In turn, Michelangelo Palloni’s frescoes, after cleaning and removing most of the repaintings and retouches from old renovations, regained their vivid colours and their details became more legible. Although the scenes from Palloni’s story of Cupid and Psyche require further restoration work, as well as merging and reconstruction of irreversibly damaged fragments of the composition, they are already a significant aesthetic accent of the gallery. Structurally reinforced stucco decorations also require the continuation of restoration work in order to fully restore the artistic finish of their surfaces. Future projects, including wall decorations and architectural elements, will gradually supplement the effects of the works completed in 2019 to restore the overall Baroque character of the entire galleries.
