The crossing point of the river is the reason for Ware’s existence.  Ware grew up at that point from the Bronze Age, or earlier, and has developed along the river since then.

A trackway, which later became known as Ermine Street, developed at the crossing point. By the Medieval period it was known as the Old North Road.

The Lea has provided Ware with a connection to the Continent, via the Thames, since the Iron-Age. It was the main route for carrying freight to London until the 20^th century, when improved roads and railway routes improved the speed of transit.  The river is still an important waterway, although used more for pleasure craft than working barges.
