Results from archaeomagnetic research on a Roman pottery kiln are presented. In a previous paper (Pares et al. 1992), a collection of samples from the kiln's heating chamber was studied and palaeodirection results were obtained. In the same paper, dating was performed on the basis of the secular variation reference curve of the inclination at Paris. In the present study, the palaeointensity was evaluated on the basis of the same collection of samples. The mean value obtained is 60.9 μT. A comparison of this value with other available archaeointensity values, obtained from neighbouring territories, confirms the date estimated by Pares et al. (1992k—the middle of the 1st Century AD.
