Foetid and pestilential, this wasteland has long been a haven for the waifs of Kenya’s fifth city, the country’s highland capital and long-distance running heartland.

Victoria Square, the major meeting point for migrants and refugees, has seen hundreds sleeping outdoors in foetid, dank conditions.

For decades, disembarking at New Street railway station could be likened to stepping into a dimly-lit concrete box filled with foetid air.
