During the renovation in the second half of the 17th century the palace was adorned in late baroque style. With a certain level of probability the frescoes can be attributed to Tylman Gamerski or his circle, due to similarity to some other works. Although predominantly known as an architect, Gamerski was also a good painter, educated in his native Low Countries and in Venice. Approximately 30% of original decoration was restored after the war.
Initially the room served as a bedchamber for master of the house. The walls were covered with frescoes depicting ancient ruins (colonnades, fountains, gates, arcades, vases) and a wooden panneling to the one sixth of its hight, which was replaced with copies of Dutch tiles after the war.
The style of decoration referring to the work of Claude Lorrain was completed with floral and mythological stuccoes in overdoor and above fireplace.
