ABSTRACT
Sweden today has nearly 1,400 privately owned buildings which have been listed as historic monuments by county administrations and the Central Board of National Antiquities. In origin they range from the 13th to the present century. Of the 350 historic monuments of stone or brick, 139 comprising between I and 7 buildings each (making 245 buildings in all) have been inspected over a five-year period in order to inventory the quantity of roofing and fayade material in a selection of privately owned historic monuments and, by means of inspection, to quantify the extent of damage.
One result of the inventory has been the identification of historic monuments in need of remedial action, as well as documentation concerning the character and extent of the measures needed. Conjointly with the inventory, environmental parameters have been described in order to ascertain connections between material degradation and air pollution. A large quantity of photographic documentation, more than 9,000 pictures, available as digital images, has been collected in the course of inspection. For reporting the extent of damage, soiling and surface vegetation, the material has been divided into five regions: the counties of Stockholm, Gotland, Malmöhus, Göteborg and Bohus and Skaraborg.
