Thatcham
Thatcham in Berkshire is often claimed as the oldest town in Britain, since its occupation can be traced back to a mesolithic hunting camp, which was discovered there beside a Post-glacial rebound period lake, and there is evidence of human occupation within and around Thatcham covering the past 13,000 years or more.
There is strong evidence to support the case that people settled in Thatcham in the Mesolithic Age (10,000BC - 4,000BC). Arguably it is the Bronze (2,500BC - 750BC) and Iron (750BC - 43AD) Ages which make Thatcham more notable than any other, and indeed makes Thatcham a nationally important place. Thatcham has strong evidence that it was settled by the Romans, then Saxons, and was mentioned in the Domesday Book. Subsequently it received medieval charters.
Thatcham has a place in the 1990 Guinness World Records as being the strongest claimant to the longest continually inhabited town in the UK.
