Occupy London Walking Tours: City of London
Time Out says
This volunteer-run tour walks you through the history of money – all the way up to the role of the City of London in the financial crisis of 2007/8, explaining along the way what the Corporation of London is, why the Queen must ask permission to enter the City and such arcana as the ‘Black-Scholes equation’. It promises to be an informative and entertaining look at the world of high finance. Meet on the cathedral steps.
