Weathering rates were calculated using the height differences between lead lettering on marble gravestones from inland urban, inland rural, coastal urban and coastal rural sites within southern Britain. All sites exhibit similar amounts and variations in rainfall over the study period for which gravestone measurements are available. Comparison of mean weathering rates suggested that the coastal urban site of Clacton had a similar weathering rate to the nearby coastal rural site. The other urban sites of Oxford, Lodge Hill and Portsmouth had similar weathering rates, despite their diverse locations and histories. The inland rural site had a significantly lower mean weathering rate than any other site. Analysis of covariance confirms that there are similarities between some sites. Linear and curvilinear regression of depth of loss against age suggests that a linear regression adequately describes the relationship over the period for which data are available, although there are problems with this simple interpretation.
