The Old Boma is Mikindani's crown jewel and one of the most atmospheric buildings on the Tanzanian coast. The thick coral-stone walls and heavy wooden doors of this German colonial fort have been meticulously restored by Trade Aid, a UK development organization that has turned it into a guesthouse and community enterprise. Even if you're not staying here, the building is worth a visit.
The Livingstone connection is genuine and moving: this is where the explorer rested before his final and fatal journey inland in 1866. A small museum section within the building documents Livingstone's final expedition and the broader history of Mikindani as a Swahili trading port. The rooftop views over the bay and the old town are excellent.
