Excavation of the basilica of the Roman town of Silchester (Calleva Atrebatum) has produced evidence for two phases of pre-Roman occupation. The earlier, probably dating to the mid-first century BC, consisted of roundhouses and pits. Around 20 BC a rectilinear steet pattern, with building plots at right angles to the streets and rectangular buildings, was laid out; later a palisaded enclosure was built. Imports included amphorae and fine pottery; Central Gaulish wares suggest an early trade connection to the south. There is some evidence of disuse before the Roman streets were laid out on a different alignment in mid first century AD.
