From the names of streets and areas (Blackfriars, Whitefriars, Ave Maria Lane, Sanctuary, Covent Garden, Holywell Row and many more) to its beautiful old churches and buildings - London is steeped in Catholic history, ancient and more recent - and who better to act as a guide than the author and broadcaster Joanna Bogle, who begins a new series of walks later this month.
