Abstract
The main aim of this work is to compare and characterize the state of decay developed in a set of 14 monuments, including churches and Pazos (Galician traditional house) of the architectural heritage of the Barbanza Peninsula (Galicia), considering its relationship with the influence of the environmental factor. A macroscopic inspection was carried out to determine the deterioration patterns. The most reported pathology across the peninsula, due to the moisture regime, was the formation of dark areas (generally as biofilms) and the lichen growth (biological colonization). Depending on the proximity to the coast, the study area was divided into two zones. Zone 1, closer to the sea (<1 km) with an important influence of sea salts and wind and zone 2, further from the sea with higher altitudes (center of the peninsula) and important rainfall, humidity and therefore, fauna growth. Crusts (to a lesser degree, because it is a mainly rural area) are more frequent in zone 1, but the state of conservation of stone is better than in zone 2 due to the concentration of urban centers that require aesthetics and constant maintenance. In zone 2, however, abandonment is greater and biological colonization (mainly by lichens and plants) is more developed along with deterioration patterns due to biological damage. The synergy of several factors such as salt, climatic conditions and spatial characteristics of the architectural heritage studied define the degree of deterioration of each heritage objective. The research has a potential contribution to the conservation measures to be undertaken.
