Abstract 390 Stockholm city buildings with sculptural decorations, or facades, of limestone or quartzitic sandstone have been investigated. The observed damage has been expressed by digital codes. The chemical analysis was mainly undertaken with SEM/EDS. The study has verified that quartzitic sandstone is more resistant towards weathering than limestone. Coarse-grained limestone with pores and cracks are most weathering-prone. Climatic conditions and air pollution are the major causes of the degradation. The data have been evaluated by means of statistical multivariate analysis. There are significant relationships between car traffic and damage, and between car traffic and soiling, also between observed damage and present degree of sulphation at limestone surfaces. The most common damage is pitting and soiling.
