From Kentnews:

An archaeological dig at a Roman fort in Sandwich has uncovered evidence of the Roman coastline – two miles inland from where it is today.

Experts from English Heritage have been carefully examining the fort as part of a month-long excavation project that is nearing its conclusion.

They have also discovered the remains of a 90-metre long stretch of collapsed wall as well as Roman coins and fragments of Italian marble dating back to the first century AD.


... which is why recent attempts at relocating the landfall/redating of Caesar's invasion don't make sense (can't find the link this a.m.!)
