The Celts do their own thing Some Celtic Settlements develop in the area now known as London.
Life is simple.
The Ancient Britons live in splendid isolation from the rest of Europe. Little evidence exists of their presence in the London area. The River Thames is strategically important for the Romans as an invasion route and for the Celts as a barrier of defence. Again the Celts use the Thames for defence. This time the Romans build a fortified port at Londinium.
