c. 700,000 BC
Pakefield cliffs, near Lowestoft
In 2000 humanly worked flints were found in the Cromer Forest-bed Formation at the base of these cliffs. These have been dated to about 700,000 years ago and at the time of their discovery they were the earliest evidence for humans in northern Europe. Slightly older evidence has since been found at Happisburgh in Norfolk.
