The paintings inside the palace were replaced with stuccos by Wirgiliusz Bauman. Significant changes were also applied to the surrounding park, which was converted from a typical classicist French park into a picturesque and then-popular landscape park. The park was also extended to include some romantic buildings and sculptures such as the "Holendernia" built between 1812 and 1814 by Aigner or two guard houses, modelled after medieval castles, built in 1832. The palace itself was also extended to include buildings that made it a full-time residence rather than a summer resort. Among the buildings added were the stables, a residential annex and a coach house. A small Gothic revival chapel was also built opposite the "Holendernia" and a newly built monument modelled after the so-called Neron's Sarcophagus and Jean-Jacques Rousseau's tomb in Paris.
