The room was originally an antechamber of Kazimierz Ludwik Bieliński. The preserved frescoes were created during second reconstruction of the palace in the second half of the 17th and are attributed to Tylman Gamerski. Approximately 75% of the original decoration preserved.
Among elements depicted are two and three masthead boats moored in the port or entering the port, small boats filled with people, lighthouses and the rocky coast. The lower parts of the walls were covered with Dutch tiles.
As in the other rooms the decoration included rich stuccos in the form of oval cartouches in overdoor, adorned with shells, acanthus twigs and grass blades. The cartouches were filled with images in sepia (only one of them preserved).
