The UK has heritage from top to toe, but nowhere more so than these towns, many of which claim to be the oldest in Britain. Exact dates of incorporation are often unavailable, and it is nigh on impossible to establish a definitive list of the oldest continuously inhabited urban settlements. This list showcases those about which factual research exists, and where dates of significant building projects exist, but there may well be other towns that can lay claim to a riper age.
