Abstract

DISCOVERIES IN AND CONSERVATION PROJECT FOR THE 17TH TO 19th-CENTURY INTERIOR DECORATION OF THE FIRST-FLOOR NORTHERN ROOM IN THE BUILDING AT 12 ŚW. JANA STREET IN KRAKÓW. THE IMPORTANCE OF RESEARCH IN CONSERVATION AND CONSTRUCTION WORKS

The paper presents the research and conservation process in the first-floor northern room in the office of the Societyof Friends of Kraków History and Heritage in a bourgeois townhouse house at 12 św. Jana Street in Kraków conducted in 2020. The interdisciplinary research methods were presented: historical – archival and library search; stratigraphic – excavations; analytical – physical-chemical and architectural; research results, conclusions and resulting project guidelines. The research uncovered interior decorations dating from three historical phases: 17th, 18th, and 19th centuries, including wall paintings, a stove arcade, a frambuga (arched niche), an interfenestral column, ceramic and wooden flooring, a canal – probably a relic of a former staircase – and a fragment of Art Nouveau wallpaper. The previously published (1961, 2018) dating of the polychrome was revised and the hypothesis on the relocation of the Mannerist ceiling was refuted. The importance of this research for the process of conservation and restoration of historic architecture, especially with a multi-phase history of transformation, is discussed. A conservation scheme was proposed. The first stage of conservation and construction works was presented.
