It is almost 50 years since the earthworks of Prae Wood (TL 122 068) SW of St Albans, Herts., were first examined by Sir Mortimer Wheeler. His publication (Wheeler and Wheeler 1936) only considered the northern half of the site (FIG. I). Recent survey of the Gorhambury estate and the environs of the Roman villa has revealed a more extensive system of the earthworks than that previously published, necessitating a re-appraisal of Wheeler's work. Wheeler's report considered Prae Wood as a native predecessor to Roman Verulamium and traced the development of the Belgic earthworks in Phase 2 and their subsequent abandonment in Phase 3. In this scheme, the first phase consisted of an inner dyke and Enclosure A, interpreted as broadly contemporary. The E side of the enclosure was formed by a N–S ditch approximately 65 m long and 4–5 m wide, at whose southern and northern ends were causeways.

2 Study of this heavily wooded area was based on the use of OS 1.2500 maps on to which results of fieldwork were added and subsequently as far as possible confirmed by aerial photographs. Available photographic coverage is confined to the S half of FIG. 2 as the N area was still covered by trees in 1957, when the photographs were taken.
