Kigoma was the inland capital of slavery, bridgehead for Tippu Tib's immense trading empire inside the dark continent. It was also the place where Stanley famously 'rescued' Livingstone, although the latter might have something other to say about that.
German colonists also made Kigoma the head of their great inland trade route, marking it with a disproportionately grand railway terminus that mistakenly foretold of bigger things to come.
Now the town is a relaxed and mildly interesting place, but far too far out of the way for most people to consider.
