Small pits with upright logs in the centre were dug into street MCC3076 between the (conjected location of a) redundant gate and the town ditch. Some of these were sealed by a thin layer of metalling showing that they are Roman in origin and late in the sequence of metalling. Their position in relation to the gate and street indicates they post-date the use of both as a ingress and egress into the town. The most likely explanation for the pits is that they were lilia - defensive devices containing sharpen posts pointing upwards (but they are not firmly dated and could be post-Roman).<1>

The possible lilia from St Peter's Street, however, are not very firmly dated and there is a small but distinct possibility that they are post-Roman in date and hence not lilia at all. This possibility is made more likely by the fact that they do not appear to have been strung out in a line across the full width of the gate which is what would be expected had they been defensive in purpose.
