The geology of a bay of Exeter Cathedral

These measured line drawings were prepared in 1998 by Stewart Brown Associates during conservation work on the south side of the nave of the cathedral. They show the clerestory (above) and aisle elevations in Bay 4. The different colours indicate the different stone types represented.

The principal stone used in the medieval church was yellow sandstone from Salcombe Regis, which forms most of the facework in the Norman period (the stonework surviving below the lower window) and in the early 14th century (the masonry above each window). Later repairs were carried out in stone from different sources, including Bath, Ketton in Northamptonshire and Portland in Dorset.
