Join Freda Dahl-Nielsen on this circular walk, uncovering deeds both good and bad in the west of the City. Find out about the founder of the Royal Exchange, Thomas Gresham,  and the man behind the Foundling Hospital, Thomas Coram, as well as taking in a church or two –  St Andrew’s Holborn and St Etheldreda, plus Hatton Garden, The Old Bailey, and one very old pub.
