There was a story a couple of weeks ago[0] about pottery dating from around 3600BCE being found at a site in Shoreditch (which was being excavated for the new Amazon HQ), suggesting London may have been inhabited considerably longer than previously thought.
That wouldn't be "London city" that would be "a village which the latter settlement of London expanded to encompass"; which is significantly different. Not longest inhabited areas, but continuously inhabited city.
