Kano:
Kano is the oldest city in West Africa (it was founded around 1400 years ago) and Nigeria’s second largest. It was a major crossroads in the trans-Saharan trade routes and, from the middle Ages, an important center for Islamic scholarship. A favored traveler destination, Kano has terrible air pollution, with traffic fumes mixed with the dusty harmattan wind.
As capital of a sharia state, alcohol was technically banned in 2004, although you can still get a drink in up market restaurants or in the bars of the Christian Sabon Gari district.
