Kasongo, Democratic Republic of the Congo

The population is just 13,798, but the town of Kasongo spreads out over a vast area, with a maze of streets and fortified places. Getting around is a persistent headache, as the 240 kilometer road to the provincial capital takes two grueling days due to its poor state. Despite the town's historic status as a key trading center, the legacy of conflict and violence remains palpable - auxiliary troops reportedly feasted on the remains of the city's defenders after its conquest. Kasongo is not for the faint of heart.
