One and all: Discovering the distinctiveness of Cornish buildings

The Cornish Buildings Group recently celebrated its 50th anniversary. Dedicated to preserving and improving Cornwall’s built heritage, the Group has marked its half-century by publishing a short history of its achievements and a volume of conference proceedings that address the question: what defines Cornish buildings? Among the factors that contribute to Cornwall’s architectural distinctiveness are the county’s geology and building stones, as well as particular building types and the designs of architects who devoted much of their career to the county, as Chris Catling reports.

Redrawing the strontium isotope map for the south-west of England

Strontium (Sr) isotope analysis has been used in archaeology for several decades now to assess movement and migration at both the individual and population level. To be as accurate as possible, however, it requires a strong baseline knowledge of the biologically available strontium in the regions from which the samples are likely to have originated.

Hollowed Ground: the archaeology of Bath’s stone mines

The hills around Bath look solid enough but below the surface they are riddled with tunnels and stone quarries. When some of these began to collapse, putting the village of Combe Down at risk, Oxford Archaeology was called in to record this vast labyrinth before it was filled with concrete. Chris Catling reports on the record they made of an industry that helped create the beautiful buildings of Georgian Bath’s ‘Golden Age’.

An archaeologist considers the contemporary (Mesolithic) Scottish scene in the next article. Here geographer David E Smith describes what Quaternary scientists know as the Storegga tsunami.
