The author presented an attempted collection of his years-long experiences and a creation of a system of assessing historical value. The system of appraisal, applied in practice, cannot be overly detailed so as to avoid falling into the trap of an excessively expanded typology of phenomena and definitions. This is the reason why it must contain simplified entries and clearly distinguished definitions, which in turn produce a rigidly hierarchised arrangement. An assessment table, devised for the author's own use, proved to be a practical aid facilitating the formulation of opinions about assorted conservation issues. The table has been accepted 'cum grano salis' as an auxiliary instrument, which in particular cases can be modified. (A) - Historical value: historical witness - historical evidence - important historical document - outstanding historical document - historical monument; (B) - Artistic value: a) diversity of forms: absence - simple - expanded - rich; b) stylistic values: styleless - simple style - expanded style - complicated style - highly representative; c) creative values: absence - imitation of forms - original work - precursory; d) role in complex: subordinate - distinguished - emphasised (dominant); e) aesthetic values: disfiguring - aesthetically indifferent - interesting - attractive - extremely attractive General artistic value: absence - mediocre average - high - outstanding - unique; (C) - Scientific value: a) value of witness/document: absence - statistic - mediocre - characteristic (for category, epoch and other features impor tant for an analysis) - high - outstanding - unique; b) importance of the object of studies: absence - statistic - mediocre - high - outstanding; c) didactic value: absence - limited as regards theme and information - limited as regards theme, expanded as regards information - multi-motif - all-sidedly and outstandingly. Cumulative assessment: scientific value:- absence - mediocre - high - outstanding - unique; (D) - Non-material value: absence - mediocre - high - outstanding - unique; (E) - Value on the scale of locality. Value on a local, regional, country, and continental scale: high - outstanding – unique. General value scale: absence - mediocre - high - outstanding - unique; (F) - Utilitarian and technical value. Utilitarian and technical values are treated as modifying assessments in an individual situation and are of importance in the case of the conservation policy but not for a fundamental assessment of historical value.
