Thames: Sacred River by Peter Ackroyd is a historical and cultural exploration of the River Thames, focusing on its significance to London and England over the centuries. The book weaves together history, mythology, literature, and personal reflection to portray the Thames not just as a physical river but as a symbol of British identity and a living entity that has shaped the nation's development. Ackroyd examines the river’s influence on art, literature, religion, and politics, while also considering its role in shaping the landscape and lives of those who live along its banks. The river is portrayed as a powerful, almost mystical presence, integral to the fabric of British life.
