The Thames: Sacred River Part 1

The Thames has been a highway, a frontier and an attack route; it has been a playground and a sewer, a source of water and a source of power. Every stretch has its own character, atmosphere and stories. "Thames: Sacred River" explores the river from source to sea. Peter Ackroyd, bestselling author of "London: The Biography", tells the story of the river and the people who have lived on and by it over the centuries. In part one, "The Mirror of History", he explores the river's geology, early history and mythology with fascinating facts and anecdotes.
