Abstract

ABSTRACT

This paper presents the results of a GPR survey carried out at the Roman town of Mariana (Corsica, France). Excavations (1959–1965 and 2000–2007) yielded a Roman street with houses and shops, an early mediaeval cathedral and a mediaeval bishop’s palace. When compared with the hypothetical town limits derived from aerial photography, old cadastral maps and the location of two cemeteries, the excavations are in an eccentric position. The principal aim of the geophysical survey was to shed more light on the Early Imperial town centre (1st–2nd century AD), which was to be found further north. The results from a fluxgate gradiometer survey demonstrated the presence of buildings with an orientation corresponding to the excavated street. In the GPR data, an orthogonal street system became noticeable and most of the buildings can be identified as private dwellings. In several parts of the town, there are indications for more than one occupation phase. For example, in the north‐western of the main survey area, the GPR results show a large building complex with deep foundations, as well as shallow walls of poor construction quality in the courtyard of this building. A trial excavation confirmed this dichotomy: it revealed solid walls with brick facings originating in the 1st or 2nd century AD, as opposed to alignments of loose boulders, not older than the 3rd century. On the basis of the GPR results, two small excavation trenches from the 1930s, one of which contained the remains of a bathhouse, can now be located exactly.
