Sokoto City, aerial view from the centre looking towards the north-west. The square building in the foreground
is Sultan Bello's mosque, originally built of sun-baked clay but now reconstructed in durable materials. Beyond
the mosque is the Palace of the Sultans, which also dates from Bello's day but has subsequently been extensively
rebuilt. In the background is the Sokoto River just above its confluence with the Rima.
