Abingdon
Abingdon in the English county of Oxfordshire (historically Berkshire) also claims to be the oldest town in Britain in continuous settlement, with people having lived there for at least 6,000 years. In 1991 evidence of a late-Iron Age enclosure of 33 hectares known as an 'oppidum' was discovered underneath the town centre. Unlike other major earthworks discovered from this period, it continued to be used as a town throughout the Roman occupation of Britain and subsequently became the Saxon settlement of Sevekesham or Seovechesham at a time when most other Roman cities were being abandoned.
In 2010 the issue of whether Thatcham or Abingdon was the longest inhabited town was disputed after the popular TV program QI claimed on its website's Fact Of The Day that it was Abingdon.
