Abstract

Background
Gradual changes in weathering rates and mechanisms are the barely visible impacts of climate change on cultural heritage. Long-term monitoring of built and archaeological heritage is therefore necessary to ascertain the nature of loss due to slow onset effects. During research at the Dublin Institute of Technology in 2011 a Legacy Indicator Tool (LegIT) for measuring the weathering of stone surfaces into the far future was developed by the author and piloted at five National Monuments in Ireland. While it is too soon to evaluate the tool in relation to long term climate change trends, this article considers the data from 5 years of exposure and provides an early assessment of the pilot study’s design and implementation.
Results
Measurements for colour, surface roughness, weight, and dimensions from the 5 year exposure of the LegIT were analysed. Comparisons between sites allows assessment of surface change under different atmospheric conditions. The indications for regional and localized weathering trends will aid managers in understanding risks and setting priorities - both for further monitoring and for conservation interventions.
Conclusions
Results from the five year pilot trial of the LegIT has allowed preliminary evaluation of its potential as a long term indicator for surface weathering. Recommendations have been made for modifications to the design, manufacture and implementation of the tool. The future aim is to compare results over time at each site, building a picture of surface weathering processes in relation to regional climatic change.
