Tom Bolton, author of London's Lost Rivers: A Walker's Guide, leads a walk tracing part of the buried River Tyburn, from Baker Street to Vauxhall Bridge. The Tyburn is one of London’s lost rivers, buried to accommodate the sprawling city and West End – but still flowing beneath the streets. This river traces and shapes the history of the West End, including the institutions of monarchy, church and department store. On this walk you will uncover layers of social history and cultural curiosity, and find out about the controversies along its route.
