Walk the hidden alleyways of the Square Mile, meeting the heroes, villains and martyrs of London.

Who really holds the power in The City? And what do they have to sacrifice to get it? Today we strive for a work/life balance but on this walk we'll be treading the steps of those who - literally - died for their work.

By revealing sights usually ignored by busy Londoners you'll look up to encounter religious fanatics, eccentric entrepreneurs, secret authors and even a viscous vulture. 

The walk lasts 90 minutes, starting from St Paul's Station, ending near Fenchurch Street. 

Groups are limited to 10 attendees, rising to 15 attendees on dates from 17 May.
