 Another feature of the gardens was a large arbor where initially the Fleming royal painter Christian Melich had his studio, but which was later selected by Queen Marie Louise Gonzaga as the venue for her literary salon.The palace had rich furnishings, with Venetian-style gilded ceilings (surviving examples of such ceilings in Poland may be seen at the Bishop's Palace in Kielce) and brown Chęciny and black Dębnik marble portals.In the 1650s, sculptor Giovanni Francesco Rossi created profuse Roman-Baroque-style marble decorations, with busts of Roman emperors and of King John II Casimir and Queen Marie Louise Gonzaga (today displayed at Gripsholm Castle in Sweden).
