Figure 3a: The Collfryn enclosure near Llansantffraid in the Vyrnwy valley. (a) shows the settlement’s cropmark ditches. Figure 3b shows a closer view of the rescue excavations by the Clwyd-Powys Archaeological Trust in 1982-83 which uncovered drainage ditches of timber-build Iron Age roundhouses and post pits representing rectangular storage buildings. The enclosure was remodelled and continued in occupation into the Roman period (Image: Clwyd-Powys Archaeological Trust 81-c-0214, 82-c-0316).
Figure 4: Cropmark enclosure at Varchoel Lane, north-east of Guilsfield. The enclosure is about 100 metres across. (Image: Clwyd-Powys Archaeological Trust, 84-c-0164).
Figure 5: Geophysical survey of the Dol-lâs enclosure, Berriew. The double-ditched enclosure is about 80 metres across internally. Gaps in both ditches indicate an entrance at the bottom. Geophysical survey can prove helpful in identifying internal subdivisions and drainage ditches are probably associated with roundhouses and other structures which may not be visible from aerial photography.

Figure 6: Old Oswestry hillfort, Shropshire. The hillfort, which occupies a lowland site, is one of the most majestic in the region. The internal area is about 5.3ha. (© Clwyd-Powys Archaeological Trust 90-mc6-0009).
Figure 7: Juxtaposition of hillfort and smaller enclosure near Llangedwyn in the Tanat Valley. To the top left is the Llwyn Bryn-dinas hillfort and to the bottom right is the Plas Uchaf enclosure, showing up as parchmarks. Excavations at Llwyn Bryn-dinas have shown an sequence extending from the Later Bronze Age into the Iron Age. The Plas Uchaf enclosure is unexcavated but seems likely to have been contemporary with the Iron Age phases at Llwyn Bryn-dinas. Excavations in the Severn valley at the Breiddin and the Collfryn have shown larger hillforts and smaller enclosures were being occupied simultaneously.

Figure 10: Hindwell, Radnorshire. North-west of the triple ditches, which have a Roman military origin, wide-spaced double ditches can be seen passing under the dense anomalies that make up the vicus. First thought to be Iron Age, these are now known to be part of a Neolithic palisaded enclosure (Image: Clwyd-Powys Archaeological Trust)

Figure 16: Cefnllys, Radnorshire. The hill, isolated by a loop in the River Ithon, has seen occupation at several times in the past. Medieval castles lie at either end of the hill, while the defences of the Iron Age hillfort are apparent just below the crest on the slope furthest from the camera Image: Clwyd-Powys Archaeological Trust, 94-c-0023
