The purpose of this interim report is to give a description of the major architectural features of the site, the evidence for their dating, and a brief account of the artifactual remains from them. This work is necessarily incomplete: only the major excavated levels are distinguished and illustrated; a detailed division of the Medieval levels into subsidiary phases has not been attempted here; and before a complete and definitive account of the artifactual remains, especially the pottery, can be given, further work must be done on the material. This may throw new light on the problems of dating.

Fig. 1 shows the area excavated, with the exception of the step trenches dug down the north side of the mound, which are of no direct relevance to the architecture of the later periods considered here, and the trenches on the west side of the mound, dug ad hoc to investigate the later Medieval structures. These are shown in Figs. 11 and 12. The continuous thin lines in Fig. 1 indicate the internal sections which were drawn from the topsoil to the point where excavation was halted but which were later removed.
