Fig. 5 The causewayed enclosure: ditch section and plan 
had either been completely removed by the very 
pronounced hollow-way, or the 2m wide stripped 
area coincided with a wide causeway. 
The causewayed ditch 
The excavated ditch section was 4m wide at the 
surface and 2.8m deep with a flat base (Figure 5). 
The sides were steep until a point c. 0.9m above the 
base at which they became almost vertical. The 
chalk through which the ditch was excavated was 
poorly structured and no tool-marks were observed 
on the sides or the base. Narrow and intermittent 
seams of tabular flint were recorded at irregular 
intervals through the chalk. Artefacts were 
retrieved by hand and the ditch fills were sampled 
for molluscs. A recut was also sampled for pollen. 
The primary fills of the ditch comprised loose 
chalk rubble nearly 1.75m deep with occasional 
nodules of flint (1354) and a series of layers of 
vacuous chalk rubble (1336, 1332) and loose chalky 
soil (1335). Two radiocarbon dates (Table 1) from 
bones in the lower fill, one from pig bone and the
