In the second of his essays on great cities which have been influenced by African migration, writer and broadcaster Lindsay Johns takes a walk around Philadelphia.

It's a city whose history is tied up with notions of America and of freedom, and as he wanders the streets of Philadelphia, Lindsay ponders the relationship between these two powerful ideas. They're not always easy to reconcile in Philadelphia - where the chronic racialised street homeless situation, the city’s poverty and stark racial divide leave him feeling a distinct lack of 'Brotherly Love' - in a city which takes that as its moniker. As Lindsay considers some of the philosophical questions which arise, he also reflects upon a community of African migrants making their home in the city with its own fascinating and surprising relationship with Philadelphia.
