The destruction of the early town by the rebels has left a thick layer of ash, destroyed buildings and smashed pottery and glasswork across the town centre and at the Sheepen river port site outside the NW corner of the town. The destruction layer, also found at Verulamium (St Albans) and Londinium (London), is famous for the charred preservation of artefacts and furniture, including a samian store, a glass store, beds and matresses, wall plaster, tessalated floors, a few human bones with wounds and even dates and plums. During excavations in 2014 at Williams and Griffin on the High Street a collection of gold and silver jewellery was discovered buried in the floor of a Roman building destroyed during the revolt. Known as the "Fenwick Treasure", it appears to have been buried just prior to the buildings destruction by a victim of the Boudican attack. The layer is important to historians as it is one of the first archaeological contexts in Britain that can be given a definitive date, as well as to archaeologists as it provides a snapshot of artifacts from 60, allowing typologies of finds to be tied into a historical timeline, for example in Samian production. The rubble from the destruction was landscaped during the rebuilding of the town that took place in the years after the revolt.
