Descrição:

From the Bronze Age to the Iron Age, the Tin Route was a major artery
that provided early settlements with access to a vital ingredient for
metal-making: tin. Copper must be alloyed with tin to make bronze,
an advance that occurred in the Near East around 2800 BCE and created a
stronger, better metal than the type used previously. This new
technology created a demand for tin, and as it is not found in many
places, the resource became an important item for trade.
One such tin route
flourished in the 1st millennium BCE. It stretched from the tin mines
in Cornwall in the far southwest of Britain, over the sea to France, and
then down to Greece and beyond. Evidence for this route is provided by
the many hillforts that sprung up along the way as trading posts.
Historians believe trade passed both ways up and down this route, as the
hillforts provide evidence of exotic artifacts, including coral and
gold. No written accounts survive from this period, but the
archaeological record shows technology and art traveled the route
between northern Europe and the Mediterranean alongside tin—thus
providing a vital link across Europe.
