The Three Windows Cabinet is a small room, located on the first floor of the main body of the Palace. It was created in King Jan III's time during the second stage of the Palace's extension, ca. 1683.
Conservation work in the Three Windows Cabinet started with preparing photographic and descriptive documentation of the room's condition. The stuccowork was subject to stratigraphic uncoverings to determine the original layers and any subsequent interventions. Then, paint-overs and secondary plaster putty were removed from the bas-relief coving.
After the above-mentioned initial work, new putty was applied, its surface was evened out, and the structure of the plasters was reinforced. As in the Banqueting Hall, two types of work supplementing the painting decoration were carried out, i.e. retouching with the use of graphic devices and partial reconstruction. Moreover, time-consuming preparations of the surface for laying gilt were completed, followed by its reconstruction.
The conservation and restoration works in the Three Windows Cabinet were conducted as a part of the “The revitalisation and digitalisation of Wilanów, the only Baroque royal residence in Poland” project. The Project had secured support from the European Regional Development Fund under the Infrastructure and Environment 2007-2013 Operational Programme, Priority XI “Culture and Cultural Heritage”, Activity 11.1.
