In this walk through trendy Shoreditch and its polar opposite neighbour, the City of London, Nick Collinson puts forward the case for the Walbrook being one of the most important rivers in the world. Lost to us for over 500 years, its waters still flow beneath our feet. As we travel the route of its vanished valley, you will hear stories of Shakespeare, raving lunatics, and an earthquake that shook London.

This tour is graded as moderate access, due to it being a walking tour covering 1.5-2 miles over busy and uneven streets, with few places to stop and rest. The nearest station is Shoreditch High Street, which has a small step and gap of 0 to 2 inches between the train and the platform, and is suitable for most, including wheelchair users.
