Around 7,000 years ago, sea levels rise across Europe forming the English Channel. Water levels continue to rise along the Kent coastline, and a small island of chalk detaches from the mainland and the Isle of Thanet is born.
The island spans 10 miles at its widest point and is separated from the mainland by a single stretch of water- the Wantsum Channel.
The Channel is two miles wide and proves an important shipping route for the Roman Empire.
