Millwall churches

I was cycling around Bermondsey and Millwall. Ended up exactly where I wanted: in ugly industrialized run down backstreets of Millwall. So I was bemused to find, amongst ruins, rundown factories and taxi depots, these churches practically one next to each other all in these 2 streets. They were all set in reapropriated failed business' offices, garages and through odd little doors and all had very inspiring names...
