The London Undone 'City of London Churches' podcast series: A journey around the magnificent and many churches of the City of London. Learn about their histories, architecture, associations, features and their spiritual lives today. 2. This week we head to St Mary Woolnoth: austere on the outside, cosy on the inside. This is the only church in the City of London that is the work of Nicholas Hawksmoor. With thanks to Melina Herman from the Cosy Coffee Corner and Tony Tucker from Friends of City Churches and the author of The Visitors Guide to City of London Churches.
