Archeological-architectural reserves of the Wawel Royal Castle were examined for the first time during the 1920s, and then in the 1970s. Subsequent assessments are partly prepared or planned. On the basis of the results of his own research and conservation undertakings, the author analyses the following problems concerning reserves: - the microclimate, - the hazards to historic substance, - the influence of functional solutions and the arrangement of the exhibition upon the degree of eventual hazards, - the specific requirements of conservation technologies. An analysis of damages observed in relics and an examination of the outcome of work carried out by using various technologies (traditional lime techniques, acrylic resins, ethyl silicates) led to the formulation of the following conclusions: - architectural relics should be conserved immediately after their discovery, - the stabilisation of humidity-thermal conditions should be achieved by taking advantage of the self-regulation of the building rather than by air conditioning devices, - functional solutions and the arrangement of the exhibition have a direct impact upon the state of the preservation of the relics, - the choice of conservation technologies should limit the use of organic solvents, and preference should be given to traditional technologies, water dispersions and microemulsions.
