FROM THE CONSERVATOR’S CHRONICLE. THE BUILDING AT 4 JAGIELLOŃSKA STREET The completion of construction and conservation works covering the historical building located at 4 Jagiellońska Street (including the annexe) which took place from 8 October 2009 to 31 May 2012 was a prerequisite for the continuation of further restoriation works according to the schedule of the project titled Alterations, Additions and Expansion of the Building Complex Located at 35 Rynek for Museum Purposes. The investor was the Historical Museum of the City of Kraków which received a subsidy from the National Fund for the Restoration of Kraków’s Historical Buildings (Narodowy Fundusz Rewaloryzacji Zabytków Krakowa). The result of these works is a harmonious marriage of the buildings’ historical features and advanced technologies which are essential for the museum to comply with 21st-century standards. Moreover, thanks to the addition of a new storey and the alterations introduced in the ground floor of the buildings adjacent to the south border wall of the property the space of the west section of the palace’s courtyard was reorganized in terms of urban planning and architectural layout. The whole building underwent complete conservation and refurbishment which included the structural reinforcement of its foundations by the addition of ferroconcrete slabs resting on microstilts to support basement walls by redistributing weights, the installation of a thermal isolation system and of vertical and horizontal dehumidifying systems. As part of the building’s modernization and its adaptation to meet contemporary standards of museum activity, a new lift shaft and air ducts for the system of mechanical ventilation were installed in the facility. New roof and cornice covering, as well as copper sheet downspouts were installed in the buildings. The external entrance stairs were also replaced. Adaptation and modernization of the wiring, the heating, and the teletechnical systems, as well as replacement of sanitary fittings guarrantee fire safety now. Proper conditions required by standard regulations pertaining to museum storage rooms, scientific workshops, conservation studios and computer rooms were created. Earthworks conducted during the construction of the transformer station and isolation of the foundations were supervised by archaeologists. Research results thus obtained greatly contribute to the knowledge about the transformations of this part of the palace complex.
